系統(tǒng)提供的各種Dialog太復雜！來個最簡單的，看圖：


簡單吧！

實現(xiàn)：

    
private Dialog 	dialog;
    private void showProgress() {
		
		if(dialog == null) {
			
			dialog =  new Dialog(this,R.style.Theme_TransparentDialog);
//			dialog.setContentView(R.layout.progress_dialog);
			dialog.setContentView(new ProgressBar(this));
			dialog.setCancelable(true);
			dialog.show();
		}
	}
	private void closeProgress() {
		
		if(dialog != null) {
			dialog.cancel();
			dialog = null;
		}
	}

  

上面的代碼中主要用到了Theme_TransparentDialog，他的定義見下面：

    
<style name="Theme_TransparentDialog">
      <item name="android:windowBackground">@android:color/transparent</item>
      <item name="android:windowFrame">@null</item>
      <item name="android:windowContentOverlay">@null</item>
      <item name="android:windowIsFloating">true</item>
      <item name="android:windowIsTranslucent">true</item>
      <item name="android:windowNoTitle">true</item>
      <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
      <item name="android:backgroundDimEnabled">false</item>
	</style> 

  

over！
