Android开发之Button事件实现与监听方法总结

本文实例总结了Android开发之Button事件实现与监听方法。分享给大家供大家参考，具体如下：

先来介绍Button事件实现的两种方法

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<Button
android:id="@+id/myButton1"
android:text=" 按钮1 "
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<Button
android:id="@+id/myButton2"
android:text=" 按钮2 "
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>

strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World, ButtonDemoActivity!</string>
<string name="app_name">ButtonDemo</string>
</resources>

第一种：

ButtonDemoActivity.java：

package com.android.ButtonDemo.activity;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class ButtonDemoActivity extends Activity {
Button myButton1,myButton2;
@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);
 myButton1=(Button)findViewById(R.id.myButton1);
 myButton2=(Button)findViewById(R.id.myButton2);
 //使用匿名类注册Button事件
 myButton1.setOnClickListener(new OnClickListener()
 {
  public void onClick(View v)
  {
   Toast.makeText(ButtonDemoActivity.this, "你点击了按钮1",Toast.LENGTH_LONG).show();
  }
 });
 myButton2.setOnClickListener(new OnClickListener()
 {
  public void onClick(View v)
  {
   Toast.makeText(ButtonDemoActivity.this, "你点击了按钮2",Toast.LENGTH_LONG).show();
  }
 });
}
}

第二种：

ButtonDemoActivity.java：

package com.android.ButtonDemo.activity;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class ButtonDemoActivity extends Activity {
Button myButton1,myButton2;
@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);
 myButton1=(Button)findViewById(R.id.myButton1);
 myButton2=(Button)findViewById(R.id.myButton2);
 myButton1.setOnClickListener(new ButtonClick());
 myButton2.setOnClickListener(new ButtonClick());
}
//创建一个类，来响应OnClickListener
class ButtonClick implements OnClickListener
{
 public void onClick(View v)
 {
  switch (v.getId()) {
  case R.id.myButton1:
   Toast.makeText(ButtonDemoActivity.this, "你点击了按钮1",Toast.LENGTH_LONG).show();
   break;
  case R.id.myButton2:
   Toast.makeText(ButtonDemoActivity.this, "你点击了按钮2",Toast.LENGTH_LONG).show();
   break;
  default:
   break;
  }
 }
}
}

再来说说Button监听方法

android button控件目前主要有如下几种监听方式:

一个button控件对应一个监听:

Button buttontest;
buttontest = (Button) findViewById(R.id.button1);
buttontest.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
 // TODO Auto-generated method stub
 Log.i("TEST", "button onClick");
}
});

多个button对应一个监听1:

start = (Button) findViewById(R.id.button1);
stop = (Button) findViewById(R.id.button2);
start.setOnClickListener(mylistener );
stop.setOnClickListener(mylistener );
View.OnClickListener mylistener = new View.OnClickListener() {
 @Override
 public void onClick(View v) {
  switch (v.getId()) {
  case R.id.button1:
   Log.d(TAG, "Start to recorder video\n");
   start_recorde();
   break;
  case R.id.button2:
   Log.d(TAG, "Stop to recorder video\n");
   stop_recorde();
   break;
  default:
   break;
  }
 }
};

多个button对应一个监听2:

public class MainActivity extends Activity implements View.OnClickListener{
//界面元素
private Button start;
private Button stop;
@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 start = (Button) findViewById(R.id.button1);
 stop = (Button) findViewById(R.id.button2);
 start.setOnClickListener(this);
 stop.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
 getMenuInflater().inflate(R.menu.activity_main, menu);
 return true;
}
@Override
public void onClick(View v) {
 switch (v.getId()) {
 case R.id.button1:
  Log.d(TAG, "Start to recorder video\n");
  break;
 case R.id.button2:
  Log.d(TAG, "Stop to recorder video\n");
  break;
 default:
  break;
 }
}
}

xml中绑定监听:

<Button
android:id="@+id/button1"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:onClick="mybuttonlistener">
</Button>

对应java代码如下:

Button btn = (Button) findViewById(R.id.button1);
public void mybuttonlistener(View target){
//do something5
}

从个人角度来讲，不推荐使用第四种实现方式。
