2.btn2=(Button)findViewById(R.id.btn2);//在xml中把button2改成btn2,为该按钮的id
3.btn2.setOnClickListener(new OnClickListener(){});
4.在OnClick()
Intent in2 = new Intent();
in2.setAction(Intent.ACTION_CALL);//指定意图动作
in2.setData(Uri.parse("tel:1836380000"));//指定电话号码
startActivity(in2);
5.在android系统中,所有系统请求,必须要在androidmainfest.xml中注册
在<application上面
<uses-permission android:name="android.permission.CALL_PHONE"/>
