简单的dialog使用。。

就当是自己记录一下学习心得了
public class MainActivity extends Activity implements OnClickListener{
Button btn_01,btn_02,btn_03,btn_04;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
public void init(){
btn_01=(Button) findViewById(R.id.btn_01);
btn_02=(Button) findViewById(R.id.btn_02);
btn_03=(Button) findViewById(R.id.btn_03);
btn_04=(Button) findViewById(R.id.btn_04);

btn_01.setOnClickListener(this);
btn_02.setOnClickListener(this);
btn_03.setOnClickListener(this);
btn_04.setOnClickListener(this);
}

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.btn_01:
dialog1();
break;
case R.id.btn_02:
dialog2();
break;
case R.id.btn_03:
dialog3();
break;
case R.id.btn_04:
dialog4();
break;


default:
break;
}
}
//简单的提醒框一
public void dialog1(){

builder.setTitle("点击信息");
builder.setMessage("你点击了查看详情");

}
//复杂提醒框二
public void dialog2(){
