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

2. 采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() {@Overridepublic 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;@Overrideprotected 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);}@Overridepublic 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{@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}public void test(View v){// 处理事件}}</span>
