创建一个布局文件 my_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="4dp"
android:text="@string/textView1"
/>
<EditText
android:id="@+id/editText_user"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView1"
android:layout_below="@+id/textView1"
android:layout_marginTop="4dp"
/>
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/editText_user"
android:layout_below="@+id/editText_user"
android:layout_marginTop="7dp"
android:text="@string/textView2"
/>
<EditText
android:id="@+id/editText_pwd"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView2"
android:layout_marginTop="4dp"
android:layout_below="@+id/textView2"
/>
</RelativeLayout>
下面是strings.xml文件：
<?
xml version="1.0" encoding="utf-8"?> <resources> <string name="app_name">demo091801</string> <string name="action_settings">Settings</string> <string name="hello_world">Hello world!</string> <string name="MyDialog">自己定义对话框</string> <string name="textView1">username</string> <string name="textView2">password</string> </resources>
在主activity_main.xml中加入一个button控件，当单击此button时即弹出自己定义的对话框：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<Button
android:id="@+id/My_Dialog"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/MyDialog"
/>
</RelativeLayout>
图形界面例如以下：
![]()
在MainActivity.java代码中为button控件设置单击事件监听，并弹出自己定义的对话框：
MainActivity.java:
package com.example.demo091801;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn1 = (Button)findViewById(R.id.My_Dialog);
btn1.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.my_dialog, null);
builder.setTitle("登陆");
builder.setView(view);
builder.setPositiveButton("登陆", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
}
);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
![]()
