編輯:關於Android編程
在我們的項目開發過程中,經常會對用戶的信息進行分組,即通過組來顯示用戶的信息,同時通過一定的查詢條件來顯示查詢後的相關用戶信息,並且通過顏色選擇器來設置列表信息的背景顏色。
下面來看看項目運行後的效果圖以及代碼結構圖:




下面通過代碼來實現整個效果。
1.主界面布局activity_main.xml
分析:主界面主要有一個Button,一個自定義搜索的ClearEditText,一個無查詢結果的TextView,一個列表信息顯示ExpandableListView。其中Button主要用來生成列表信息。
2.自定義的ClearEditText的搜索框CliearEditText.java
package com.example.myexpandabledemo;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnFocusChangeListener;
import android.view.animation.Animation;
import android.view.animation.CycleInterpolator;
import android.view.animation.TranslateAnimation;
import android.widget.EditText;
public class ClearEditText extends EditText implements
OnFocusChangeListener, TextWatcher {
/**
* 刪除按鈕的引用
*/
private Drawable mClearDrawable;
public ClearEditText(Context context) {
this(context, null);
}
public ClearEditText(Context context, AttributeSet attrs) {
//這裡構造方法也很重要,不加這個很多屬性不能再XML裡面定義
this(context, attrs, android.R.attr.editTextStyle);
}
public ClearEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
private void init() {
//獲取EditText的DrawableRight,假如沒有設置我們就使用默認的圖片

}
mClearDrawable.setBounds(0, 0, mClearDrawable.getIntrinsicWidth(), mClearDrawable.getIntrinsicHeight());
setClearIconVisible(false);
setOnFocusChangeListener(this);
addTextChangedListener(this);
}
/**

*/
@Override

boolean touchable = event.getX() > (getWidth()

&& (event.getX() < ((getWidth() - getPaddingRight())));
if (touchable) {
this.setText();
}
}
}
return super.onTouchEvent(event);
}
/**
* 當ClearEditText焦點發生變化的時候,判斷裡面字符串長度設置清除圖標的顯示與隱藏
*/

}
/**

*/
@Override

int after) {
setClearIconVisible(s.length() > 0);
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void afterTextChanged(Editable s) {
}
/**
* 設置晃動動畫
*/
public void setShakeAnimation(){
this.setAnimation(shakeAnimation(5));
}
/**
* 晃動動畫
* @param counts 1秒鐘晃動多少下
* @return

3.漢字拼音排序所需要的漢字轉拼音:CharacterParser.java

public String getName() {

}
6.ExpandaleListView 適配器MyExpandableAdapter.java

}
分析:
GroupHolderView:用於顯示組信息
ChildHolderView:用於顯示組下成員信息。包括一個LinearLayout,一個ImageView,一個TextVIew
private List
private List> mChild;包含所有的組下成員信息
public void updateListView(List根據傳入的mGroup,mChild來更新列表信息。mGroup,List > mChild) { this.mGroup = mGroup; this.mChild = mChild; notifyDataSetChanged(); }
7.GroupHolderView類所對應的activity_group.xml
分析:根據android:background=@drawable/my_child_selector 顏色選擇器來設置每個列表行(選中或正常)的背景色。

用於生成列表信息
private List根據 res->array定義的字符數組,轉化為ListfilledData(String[] date)
private void filterData(String filterStr) {
根據查詢條件更新列表信息,
假如:filterStr = “g”;
2.如果查詢的結果為空,直接給出“未搜索到結果”提示;
3.如果Group中包含filterStr,GroupMemberBean sortModel 直接加入groupFilterList,並標記已加入isAddGroup = true;
如果Child中包含filterStr,定義臨時的tempFilterList,GroupMemberBean sortChildModel加入到childFilterList,如果groupFilterList不包含其父組,並將其父加入到groupFilterList,並標記已加入isAddGroup=true;
最後如果isAddGroup=true,將tempFilterList加入到childFilterList。
4.通過myAdapter.updateListView(groupFilterList, childFilterList),更新列表信息。

Android實現圖片多點觸控自由伸縮
簡介作為Android開發者,我們經常需要自定義控件,比如下面我們說的實現圖片的多點觸控和伸縮釋放,這也是由於用戶已經有這樣的常識了,那就是看見有圖片的地方就可以點擊查看
Android自定義可編輯、刪除的側滑LisitView
最近由於項目的需要,自定義了一個具有側滑功能的listview,側滑後可以點擊編輯、刪除。好了,大家先看一下效果圖,畢竟是看臉的世界。 好了,我要先講一下思路,
Android N 對Doze(打盹)模式優化
