Android全屏對話框(附帶延時關閉效果)

自定義style,設置全屏屬性

<resources>

    <style name="AppTheme" parent="Android:Theme.Black"/>
    <style name="processDialog" >
        <item name="android:windowIsFloating">true</item><!--是否浮現在activity之上-->
        <item name="android:windowFullscreen">true</item> 
        <item name="android:windowIsTranslucent">false</item><!--半透明--> 
        <item name="android:windowNoTitle">true</item><!--無標題--> 
        <item name="android:windowBackground">@android:color/transparent</item><!--背景透明--> 
        <item name="android:backgroundDimEnabled">true</item><!--模糊--> 
        <item name="android:backgroundDimAmount">0.5</item>
        <item name="android:alpha">0.3</item>
    </style> 

</resources>

代碼中加載這個view並把view set到dialog上,這樣全屏的dialog就完成了

mView = LayoutInflater.from(this).inflate(R.layout.process_dialog, null); 
 processDialog = new Dialog(LogActivity.this, R.style.processDialog); 
 processDialog.setCancelable(false);
 processDialog.setContentView(mView); 
mAutoCloseDialog = new AutoCloseDialog(processDialog);
mAutoCloseDialog.show(Prefs.DIALOG_DISPLAY_TIME);

接下來用一個封裝好的類,做一個延時關閉的效果

import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;

import android.app.Dialog;

public class AutoCloseDialog{ 
   
    private Dialog dialog; 
    private ScheduledExecutorService executor = Executors.newSingleThreadScheduledExecutor(); 
     
    public AutoCloseDialog(Dialog dialog){ 
        this.dialog = dialog; 
    } 
     
    public void show(long duration){ 
     
        Runnable runner = new Runnable() { 
            public void run() { 
                dialog.dismiss(); 
            } 
        }; 
        executor.schedule(runner, duration, TimeUnit.MILLISECONDS);
        dialog.show();
    } 
     
}
