Android對話框風格的視窗

這種對話框本質上還是視窗，隻是把視窗的Activity的風格設為對話框風格即可

Main.xml

<LinearLayout 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"

    tools:context=".MainActivity"

    android:orientation="vertical">

    <Button android:id="@+id/but"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:text="點選"/>

</LinearLayout>

Main.java

package com.example.dialogwindow;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

import android.view.View;

import android.widget.Button;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button but=(Button) super.findViewById(R.id.but);

but.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

//結束該Activity

finish();

}

});

}

}

修改我們的Manifest檔案，設定視窗的風格

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.example.dialogwindow"

    android:versionCode="1"

    android:versionName="1.0" >

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="18" />

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.example.dialogwindow.MainActivity"

            android:label="@string/app_name" 

            android:theme="@android:style/Theme.Dialog">

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>
