安卓中四种点击事件

1. 创建内部类。定义点击事件

<span style="font-size:18px;">package com.example.test;

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

public class MainActivity extends Activity {
    private Button testButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        testButton = (Button) findViewById(R.id.testButton);
        
        // 设置点击处理时间
        testButton.setOnClickListener(new MyListener());
    }
    
     /* 
      * 创建的内部类。处理点击事件
      *
      * */
    private class MyListener implements OnClickListener{

		@Override
		public void onClick(View v) {
			
			//  处理的时间
		}
    	
    }
    
}
</span>

2. 採用匿名内部类创建点击事件

  

<span style="font-size:18px;">package com.example.test;

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

public class MainActivity extends Activity {
    private Button testButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        testButton = (Button) findViewById(R.id.testButton);
        
        // 设置点击处理时间
        testButton.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				
				//处理的事件 
				
			}
		}); 
       
   }
}
</span>

3. 在接口里面实现点击处理事件

<span style="font-size:18px;">package com.example.test;

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

public class MainActivity extends Activity implements OnClickListener {
	private Button testButton;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		testButton = (Button) findViewById(R.id.testButton);

		// 设置点击处理事件
		testButton.setOnClickListener(this);
	}

	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.testButton:
			// 处理的事件
			break;

		default:
			break;
		}

	}
}
</span>

4.在布局中绑定点击方法

布局：

<span style="font-size:18px;"><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/testButton"
        <span style="color:#ff0000;">android:onClick="test"</span>
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="76dp"
        android:text="Button" />

</RelativeLayout>
</span>

Java代码

<span style="font-size:18px;">package com.example.test;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity{
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

	}
	
	
	public void test(View v){
		// 处理事件
	}

}
</span>
