Android中button的onClick事件几种方法

利用三种方法&＃xff0c;学习button的监听事件。

方法一源码如下&＃xff1a;

package com.example.androidtest;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

import android.view.View;

import android.widget.TextView;

import android.view.View.OnClickListener;

import android.widget.Button;

//import android.text.Editable;

//import android.text.TextWatcher;

import android.widget.EditText;

public class MainActivity extends Activity

{

&＃64;Override

protected void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button button1 &＃61; (Button)findViewById(R.id.button1);

Button button2 &＃61; (Button)findViewById(R.id.button2);

//方法一&＃xff1a;

//增加事件响应

button1.setOnClickListener(new Button.OnClickListener()

{

public void onClick(View v)

{

Intent intent &＃61;new Intent();

intent.setClass(MainActivity.this, TestActivity.class);

MainActivity.this.startActivity(intent);

}

});

button2.setOnClickListener(new Button.OnClickListener()

{

public void onClick(View v)

{

Intent intent &＃61;new Intent();

intent.setClass(MainActivity.this, TActivity.class);

MainActivity.this.startActivity(intent);

}

});

}

方法二&＃xff1a;

package com.example.androidtest;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

import android.view.View;

import android.widget.TextView;

import android.view.View.OnClickListener;

import android.widget.Button;

//import android.text.Editable;

//import android.text.TextWatcher;

import android.widget.EditText;

public class MainActivity extends Activity

{

&＃64;Override

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button button1 &＃61; (Button)findViewById(R.id.button1);

Button button2 &＃61; (Button)findViewById(R.id.button2);

}

//方法二&＃xff1a;

public void myClickHandler(View target){

switch (target.getId()) {

case R.id.button1:

Intent music&＃61;new Intent();

music.setClass(MainActivity.this, TestActivity.class);

MainActivity.this.startActivity(music);

// setTitle("myClickHandler01");

break;

case R.id.button2:

// setTitle("myClickHandler02");

Intent moive&＃61;new Intent();

moive.setClass(MainActivity.this, TActivity.class);

MainActivity.this.startActivity(moive);

break;

}

}

}

方法三&＃xff1a;

package com.example.androidtest;

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.view.Menu;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

import android.view.View;

import android.widget.TextView;

import android.view.View.OnClickListener;

import android.widget.Button;

//import android.text.Editable;

//import android.text.TextWatcher;

import android.widget.EditText;

public class MainActivity extends Activity

{

protected void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

//方法三&＃xff1a;

public void myClickHandler01(View target){

//设置activity的头标题

// setTitle("myClickHandler01");

Intent music&＃61;new Intent();

music.setClass(MainActivity.this, TestActivity.class);

MainActivity.this.startActivity(music);

}

public void myClickHandler02(View target){

//设置activity的头标题

// setTitle("myClickHandler02");

Intent moive&＃61;new Intent();

moive.setClass(MainActivity.this, TActivity.class);

MainActivity.this.startActivity(moive);

}

}
