关于activity绑定的dialog的用法

来源：互联网发布：韩顺平js笔记编辑：程序博客网时间：2024/05/05 21:20

当有的activity有返回建的时候，我们可以设置点击返回显示弹出dialog的消息，然后去dialog处理，是返回主页面，还是结束当前的activity都可以

public class ExitNoDateDialog extends Dialog{

//dailog
private Context context;
public ExitNoDateDialog(Context context) {
super(context);
this.context = context;

}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);//弹出窗体
getWindow().setBackgroundDrawableResource(android.R.color.transparent);
setContentView(R.layout.exitnodatadialog);

TextView exit = (TextView) findViewById(R.id.exit);
TextView noexit = (TextView) findViewById(R.id.noexit);

exit.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
dismiss();
if(context instanceof AddOrderActivity){//if判断，如果这个activity在当前的activity，点击回退，就回到主页
Intent intent = new Intent(context,
WalletMainActivity.class);
context.startActivity(intent);
}else{
((Activity) context).finish();//否则就回到上一个activity，这里思路有很多各自发挥，大概都是在这处理，如果你不想在dialog处理也可以
}
}
});
noexit.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
dismiss();

}
});
}

}
