请大家帮忙，Android Progressdialog dismiss 后,Progressdialog关闭 ，触碰屏幕出现灰色遮罩层，如progressdialog 的灰色背景，按下返回键后，恢复正常，
android stdio 下信息:
D/Surface: Surface::disconnect(this=0xb78fda70,api=1)
D/OpenGLRenderer: CanvasContext() 0xb75e5ff8 initialize 0xb75f2628 //
D/Surface: Surface::connect(this=0xb75f2620,api=1)
D/mali_winsys: new_window_surface returns 0x3000
D/Surface: Surface::allocateBuffers(this=0xb75f2620)
D/Surface: Surface::disconnect(this=0xb75f2620,api=1)
在Activity下代码:
private ProgressDialog mDialog;
private void showProgressDialog(){
if(mDialog==null){
mDialog = new ProgressDialog(this);
mDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);//设置风格为圆形进度条
mDialog.setMessage("正在加载 ，请等待...");
mDialog.setMax(100);
mDialog.setIndeterminate(false);//设置进度条是否为不明确
mDialog.setCancelable(true);//设置进度条是否可以按退回键取消
mDialog.setCanceledOnTouchOutside(false);
mDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialog) {
// TODO Auto-generated method stub
mDialog=null;
}
});
mDialog.show();
}
}
private void closeProgressDialog(){
if(mDialog!=null){
mDialog.dismiss();
mDialog=null;
}
}
