【移动应用开发技术】androidstudio按钮监听的示例分析

这篇文章将为大家详细讲解有关androidstudio按钮监听的示例分析，在下觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。Android是一种基于Linux内核的自由及开放源代码的操作系统，主要使用于移动设备，如智能手机和平板电脑，由美国Google公司和开放手机联盟领导及开发。1.匿名内部类public

class

MainActivity

extends

AppCompatActivity

implements

View.OnClickListener

{

@Override

protected

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button

btn1

=

findViewById(R.id.btn1);//匿名内部类

btn1.setOnClickListener(new

OnClickListener()

{

@Override

public

void

onClick(View

v)

{

Toast.makeText(getApplicationContext(),

“你点击了按钮1”,

Toast.LENGTH_LONG).show();

}

});

}2.内部类public

class

MainActivity

extends

AppCompatActivity

{

@Override

protected

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button

btn2

=

findViewById(R.id.btn2);

Btn2CLickListener

btn2CLickListener

=

new

Btn2CLickListener();

btn2.setOnClickListener(btn2CLickListener);

}

class

Btn2CLickListener

implements

View.OnClickListener{

@Override

public

void

onClick(View

v){

Toast.makeText(getApplicationContext(),“你点击了按钮2”,Toast.LENGTH_LONG).show();

}

}3外部类**MainActivity.java：

public

class

MainActivity

extends

AppCompatActivity{

protected

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

Button

btn3

=

findViewById(R.id.btn3);

Btn3ClickListener

btn3CLickListener

=

new

Btn3ClickListener(getApplicationContext());

btn3.setOnClickListener(btn3CLickListener);

}

Btn3ClickListener.java：4自身activitypublic

class

MainActivity

extends

AppCompatActivity

implements

View.OnClickListener

{

protected

void

onCreate(Bundle

savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button

btn4

=

findViewById(R.id.btn4);//main

activity

btn4.setOnClickListener(this);

}

public

void

onClick(View

v)

{

Toast.makeText(getApplicationContext(),

“你点击了按钮4”,

Toast.LENGTH_SHORT).show();

}

}5直接绑定到标签activity_main.xml：添加android:onClick=“myClick”。如下所示：MainActivity.java：public

class

MainActivity

extends

AppCompatActivity

implements

View.OnClickListener

{

public

void

myClick(View

view)

{

Toast.makeText(getApplicationContext(),

“你点击了按钮5”,

Toast.
