Android 自定義對話框，進度條，下拉刷新等

編輯：關於Android編程

這個demo集合了自定義對話框，進度條，下拉刷新以及popup彈出框等。是學習了網上開源項目後，抽取集合了常用對話框，進度條，下拉刷新以及popup彈出框等。現在結構目錄簡單，更易於學習和擴展使用。注釋都卸載代碼。下面進行簡單的介紹以及部分代碼展示。

2、項目結構圖

\

這上面項目結構圖也是一目了然，有什麼功能展示。大家也看到了，這上面類有點多，如果全部貼出來，不大可能，有興趣下載本文源碼。

3、看看基礎類BaseActivity

我就貼一下基礎類，還有實現類。因為這些一段段代碼易於其他項目使用。

 

package com.org.base;

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import com.example.activity.R;
import com.example.activity.R.layout;
import com.org.dialog.LoadingDialog;
import com.org.view.HandyTextView;

import android.os.AsyncTask;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.util.Log;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Toast;
import android.app.Activity;
import android.content.Intent;

public class BaseActivity extends Activity {
	protected LoadingDialog mLoadingDialog;
	/**
	 * 屏幕的寬度、高度、密度
	 */
	protected int mScreenWidth;
	protected int mScreenHeight;
	protected float mDensity;
	//異步加載任務的list
	protected List> mAsyncTasks = new ArrayList>();
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		mLoadingDialog = new LoadingDialog(this, 請求提交中);
		DisplayMetrics metric = new DisplayMetrics();
		getWindowManager().getDefaultDisplay().getMetrics(metric);
		mScreenWidth = metric.widthPixels;
		mScreenHeight = metric.heightPixels;
		mDensity = metric.density;
	}
	
	protected void putAsyncTask(AsyncTask asyncTask) {
		mAsyncTasks.add(asyncTask.execute());
	}
	
	protected void clearAsyncTask() {
		Iterator> iterator = mAsyncTasks
				.iterator();
		while (iterator.hasNext()) {
			AsyncTask asyncTask = iterator.next();
			if (asyncTask != null && !asyncTask.isCancelled()) {
				asyncTask.cancel(true);
			}
		}
		mAsyncTasks.clear();
	}

	protected void showLoadingDialog(String text) {
		if (text != null) {
			mLoadingDialog.setText(text);
		}
		mLoadingDialog.show();
	}

	protected void dismissLoadingDialog() {
		if (mLoadingDialog.isShowing()) {
			mLoadingDialog.dismiss();
		}
	}
	
	/** 短暫顯示Toast提示(來自res) **/
	protected void showShortToast(int resId) {
		Toast.makeText(this, getString(resId), Toast.LENGTH_SHORT).show();
	}

	/** 短暫顯示Toast提示(來自String) **/
	protected void showShortToast(String text) {
		Toast.makeText(this, text, Toast.LENGTH_SHORT).show();
	}

	/** 長時間顯示Toast提示(來自res) **/
	protected void showLongToast(int resId) {
		Toast.makeText(this, getString(resId), Toast.LENGTH_LONG).show();
	}

	/** 長時間顯示Toast提示(來自String) **/
	protected void showLongToast(String text) {
		Toast.makeText(this, text, Toast.LENGTH_LONG).show();
	}

	/** 顯示自定義Toast提示(來自res) **/
	protected void showCustomToast(int resId) {
		View toastRoot = LayoutInflater.from(BaseActivity.this).inflate(
				R.layout.common_toast, null);
		((HandyTextView) toastRoot.findViewById(R.id.toast_text))
				.setText(getString(resId));
		Toast toast = new Toast(BaseActivity.this);
		toast.setGravity(Gravity.CENTER, 0, 0);
		toast.setDuration(Toast.LENGTH_SHORT);
		toast.setView(toastRoot);
		toast.show();
	}

	/** 顯示自定義Toast提示(來自String) **/
	protected void showCustomToast(String text) {
		View toastRoot = LayoutInflater.from(BaseActivity.this).inflate(
				R.layout.common_toast, null);
		((HandyTextView) toastRoot.findViewById(R.id.toast_text)).setText(text);

		toast.setGravity(Gravity.CENTER, 0, 0);
		toast.setDuration(Toast.LENGTH_SHORT);
		toast.setView(toastRoot);
		toast.show();
	}

	/** Debug輸出Log日志 **/
	protected void showLogDebug(String tag, String msg) {
		Log.d(tag, msg);
	}

	/** Error輸出Log日志 **/
	protected void showLogError(String tag, String msg) {
		Log.e(tag, msg);
	}

	/** 通過Class跳轉界面 **/
	protected void startActivity(Class cls) {
		startActivity(cls, null);
	}

	/** 含有Bundle通過Class跳轉界面 **/
	protected void startActivity(Class cls, Bundle bundle) {
		Intent intent = new Intent();
		intent.setClass(this, cls);
		if (bundle != null) {
			intent.putExtras(bundle);
		}
		startActivity(intent);
	}
	
	/** 默認退出 **/
	protected void defaultFinish() {
		super.finish();
	}
}

 

4、BasePopupWindow

 

 

package com.org.base;

import android.annotation.TargetApi;
import android.content.Context;
import android.graphics.drawable.BitmapDrawable;
import android.os.Build;
import android.util.AttributeSet;
import android.view.Gravity;
import android.view.View;
import android.widget.PopupWindow;

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public abstract class BasePopupWindow extends PopupWindow {

	protected View mContentView;
	protected onSubmitClickListener mOnSubmitClickListener;

	public BasePopupWindow() {
		super();
	}

	public BasePopupWindow(Context context, AttributeSet attrs,
			int defStyleAttr, int defStyleRes) {
		super(context, attrs, defStyleAttr, defStyleRes);
	}

	public BasePopupWindow(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
	}

	public BasePopupWindow(Context context, AttributeSet attrs) {
		super(context, attrs);
	}

	public BasePopupWindow(Context context) {
		super(context);
	}

	public BasePopupWindow(int width, int height) {
		super(width, height);
	}

	public BasePopupWindow(View contentView, int width, int height,
			boolean focusable) {
		super(contentView, width, height, focusable);
	}

	public BasePopupWindow(View contentView) {
		super(contentView);
	}

	@SuppressWarnings(deprecation)
	public BasePopupWindow(View contentView, int width, int height) {
		super(contentView, width, height, true);
		mContentView = contentView;
		setBackgroundDrawable(new BitmapDrawable());
		initViews();
		initEvents();
		init();
	}

	public abstract void initViews();

	public abstract void initEvents();

	public abstract void init();

	public View findViewById(int id) {
		return mContentView.findViewById(id);
	}

	/**
	 * 顯示在parent的上部並水平居中
	 * 
	 * @param parent
	 */
	public void showViewTopCenter(View parent) {
		showAtLocation(parent, Gravity.TOP | Gravity.CENTER_HORIZONTAL, 0, 0);
	}

	/**
	 * 顯示在parent的中心
	 * 
	 * @param parent
	 */
	public void showViewCenter(View parent) {
		showAtLocation(parent, Gravity.CENTER, 0, 0);
	}

	/**
	 * 添加確認單擊監聽
	 * 
	 * @param l
	 */
	public void setOnSubmitClickListener(onSubmitClickListener l) {
		mOnSubmitClickListener = l;
	}

	public interface onSubmitClickListener {
		void onClick();
	}

}

 

5、BaseArrayListAdapter

package com.org.base;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;

//基本的適配器
public class BaseArrayListAdapter extends BaseAdapter {

	protected Context mContext;
	protected LayoutInflater mInflater;
	protected List mDatas = new ArrayList();

	//String數組添加數據源
	public BaseArrayListAdapter(Context context, String... datas) {
		mContext = context;
		mInflater = LayoutInflater.from(context);
		if (datas != null && datas.length > 0) {
			mDatas = Arrays.asList(datas);
		}
	}

	//用list方式添加數據源
	public BaseArrayListAdapter(Context context, List datas) {
		mContext = context;
		mInflater = LayoutInflater.from(context);
		if (datas != null && datas.size() > 0) {
			mDatas = datas;
		}
	}

	@Override
	public int getCount() {
		return mDatas.size();
	}

	@Override
	public Object getItem(int position) {
		return mDatas.get(position);
	}

	@Override
	public long getItemId(int position) {
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		return null;
	}
}

6、實現自定義對話框，進度條以及popup彈出框，主MainActivity

 

 

package com.example.activity;

import com.org.base.BaseActivity;
import com.org.dialog.EditTextDialog;
import com.org.dialog.SimpleListDialog;
import com.org.dialog.SimpleListDialog.onSimpleListItemClickListener;
import com.org.popupwindow.ChatPopupWindow;
import com.org.popupwindow.ChatPopupWindow.onChatPopupItemClickListener;
import com.viw.adapt.CheckListDialogAdapter;

import android.R.layout;
import android.content.DialogInterface;
import android.os.Bundle;
import android.os.Handler;
import android.util.TypedValue;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.RelativeLayout;

public class MainActivity extends BaseActivity 
implements 
OnClickListener,
onChatPopupItemClickListener{

	protected SimpleListDialog mDialog;
	private int mCheckId = 0;
	private ChatPopupWindow mChatPopupWindow;
	private int mWidth;
	private int mHeaderHeight;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		findViewById(R.id.button1).setOnClickListener(this);
		findViewById(R.id.button2).setOnClickListener(this);
		findViewById(R.id.button3).setOnClickListener(this);
		findViewById(R.id.button4).setOnClickListener(this);
		findViewById(R.id.button5).setOnClickListener(this);		
		initPopupWindow();
	}

	public void onSimpleListItem() {
		String[] modes = new String[]{測試一,測試二,測試三};
		mDialog = new SimpleListDialog(this);
		mDialog.setTitle(單選框);
		mDialog.setTitleLineVisibility(View.GONE);
		mDialog.setAdapter(new CheckListDialogAdapter(mCheckId, this, modes));
		//用匿名內部類實現接口監聽
		mDialog.setOnSimpleListItemClickListener(new DialogItemClickListener());
		mDialog.show();
	}

	protected class DialogItemClickListener implements
			onSimpleListItemClickListener {

		@Override
		public void onItemClick(int position) {
			mCheckId = position;
		}
	}

	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.button1:

			showLoadingDialog(正在加載。。。);
			new Handler().postDelayed(new Runnable() {
				@Override
				public void run() {
					dismissLoadingDialog();

				}
			}, 10000);
			break;
		case R.id.button2:
			onSimpleListItem();
			break;
		case R.id.button3:
			onEditTextDialog();
			break;		
		case R.id.button4:
			RelativeLayout layoutShow = (RelativeLayout)findViewById(R.id.layoutShow);
			mChatPopupWindow.showAtLocation(layoutShow, Gravity.RIGHT
					| Gravity.TOP, -10, mHeaderHeight + 10);
			break;
		case R.id.button5:
			startActivity(PullRefreshListViewActivity.class);
			break;
		default:
			break;
		}

	}

	private void onEditTextDialog() {
		final EditTextDialog mEditTextDialog = new EditTextDialog(this);
		mEditTextDialog.setTitle(填寫推薦人);
		mEditTextDialog.setButton(取消,
				new DialogInterface.OnClickListener() {

					@Override
					public void onClick(DialogInterface dialog, int which) {
						mEditTextDialog.cancel();
					}
				}, 確認, new DialogInterface.OnClickListener() {

					@Override
					public void onClick(DialogInterface dialog, int which) {
						String text = mEditTextDialog.getText();
						if (text == null) {
							mEditTextDialog.requestFocus();
						} else {
							mEditTextDialog.dismiss();
						}
					}
				});
		mEditTextDialog.show();
	}
	
	//初始化PopupWindow
	protected void initPopupWindow() {
		mWidth = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
				130, getResources().getDisplayMetrics());
		mHeaderHeight = (int) TypedValue.applyDimension(
				TypedValue.COMPLEX_UNIT_DIP, 48, getResources()
						.getDisplayMetrics());
		mChatPopupWindow = new ChatPopupWindow(this, mWidth,
				LayoutParams.WRAP_CONTENT);
		mChatPopupWindow.setOnChatPopupItemClickListener(this);
	}

	
	//以下是popupwindow的選擇監聽事件
	@Override
	public void onVoiceModeClick() {
		showCustomToast(pop監聽1);
		
	}

	@Override
	public void onCreateClick() {
		showCustomToast(pop監聽2);
	}

	@Override
	public void onSynchronousClick() {
		showCustomToast(pop監聽3);
		
	}

}

 

7、下拉刷新PullRefreshListViewActivity

package com.example.activity;

import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import com.org.base.BaseActivity;
import com.org.view.PullRefreshListView;
import com.org.view.PullRefreshListView.OnCancelListener;
import com.org.view.PullRefreshListView.OnRefreshListener;
import com.viw.adapt.CheckListDialogAdapter;

public class PullRefreshListViewActivity extends BaseActivity
implements
OnRefreshListener,
OnCancelListener,
OnItemClickListener{
	private PullRefreshListView mRefreshListView;
	String[] modes = new String[]{測試一,測試二,測試三};
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_refresh);
		
		initViews();
	}
	
	
	protected void initViews() {
		mRefreshListView = (PullRefreshListView) findViewById(R.id.otherfeedlist_mmrlv_list);
		//適配器我隨便用了一個
		mRefreshListView.setAdapter(new CheckListDialogAdapter(1, this, modes));
		mRefreshListView.setOnItemClickListener(this);
		mRefreshListView.setOnRefreshListener(this);
		mRefreshListView.setOnCancelListener(this);
	}


	@Override
	public void onCancel() {
		//取消刷新
		mRefreshListView.onRefreshComplete();
	}


	@Override
	public void onRefresh() {
		
		//異步加載線程
		putAsyncTask(new AsyncTask() {
			@Override
			protected Boolean doInBackground(Void... params) {
				try {
					Thread.sleep(2000);
				} catch (InterruptedException e) {

				}
				return null;
			}

			@Override
			protected void onPostExecute(Boolean result) {
				super.onPostExecute(result);
				//這裡寫刷新adapt數據就行可以了
				
				
				mRefreshListView.onRefreshComplete();
			}
		});
		
	}

	@Override
	public void onItemClick(AdapterView parent, View view, int position,
			long id) {
		// listview的單擊事件就不寫了
		
	}
}
