本章将自己学习的自定义dialog和大家分享下

首先大家先看下效果

接下来我们就看代码:

1. MainActivity

public class MainActivity extends Activity implements MyListener {
private MyDialog dialog;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dialog = new MyDialog(MainActivity.this);
}

public void click(View view) {
dialog.getDialog(this).setTitle("退出当前账号").setMsg("在连续登陆15天,就可变身为QQ达人。退出QQ可能会使你现有记录归零,确定退出?").show();
}

@Override
public void configm() {
Toast.makeText(MainActivity.this, "确定", 0).show();
}

@Override
public void cancel() {
Toast.makeText(MainActivity.this, "取消", 0).show();
}

}

2. MyDialog

public class MyDialog implements OnClickListener {
private Dialog alert;
private Context c;
private TextView title, msg;
private Button neg, pos;
private MyListener listener;

public MyDialog(Context c) {
this.c = c;
}

public MyDialog getDialog(MyListener listener) {
this.listener = listener;
alert = new Dialog(c, R.style.AlertDialogStyle);
View alertView = View.inflate(c, R.layout.view_alertdialog, null);
alert.setContentView(alertView);
title = (TextView) alertView.findViewById(R.id.txt_title);
msg = (TextView) alertView.findViewById(R.id.txt_msg);
neg = (Button) alertView.findViewById(R.id.btn_neg);
pos = (Button) alertView.findViewById(R.id.btn_pos);
neg.setOnClickListener(this);
pos.setOnClickListener(this);
return this;
}

public MyDialog setTitle(String m_title) {
title.setText(m_title);
return this;
}

public MyDialog setMsg(String m_content) {
msg.setText(m_content);
return this;

}

public void show() {
alert.show();
}

@Override
public void onClick(View v) {
if (v == neg) {
listener.configm();
alert.dismiss();
} else if (v == pos) {
listener.cancel();
alert.dismiss();

}

}

}

3.接口

public interface MyListener {
void configm();
void cancel();
}
