Android---04---基礎2

昨天繼續講解了安卓中簡單的Widget

package com.example.test_uiwidget;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {
	private EditText et;
	private Button bt;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		
		
		 bt=(Button)findViewById(R.id.mybutton);
		//1,找到組件
		 et=(EditText)findViewById(R.id.myedittext);
		 bt.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				
				
				//2,獲得內容
				String text=et.getText().toString();
				//3.打印
				//Logcat 日志
				System.out.println(text);
				Toast.makeText(getApplicationContext(), text, Toast.LENGTH_SHORT).show();
			}
		});
		
	
	}
//	//當按鈕點擊時，調用方法
//	public void click(View v)
//	{
//		
//	}


	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

}
