我想在执行异步任务的ever doInBackground()方法时显示动画应用程序徽标,而不是进度对话框或进度条 请参阅Expedia Android应用程序的参考资料 请帮帮我。提前感谢…正如Rank指出的那样如何在android中执行doInBackground()时显示动画(如应用程序的徽标),android,android-asynctask,jquery-animate,Android,Android Asynctask,Jquery Animate,我想在执行异步任务的ever doInBackground()方法时显示动画应用程序徽标,而不是进度对话框或进度条 请参阅Expedia Android应用程序的参考资料 请帮帮我。提前感谢…正如Rank指出的那样 @Override protected void onPreExecute() { //do animation stuff here super.onPreExecute(); } 然
@Override
protected void onPreExecute() {
//do animation stuff here
super.onPreExecute();
}
然后
protected void onPostExecute(Object result) {
//end animation here
super.onPostExecute();
}
您应该在onPreExecute()中使用自定义对话框
Dialog mDialog=新建对话框(mContext,
android.R.style.Theme(半透明的NoTitleBar);
mDialog.setContentView(R.layout.progressbar);
mDialog.setCancelable(假);
mDialog.show()`在这里输入代码`
>>…这是您自定义对话框栏的布局…。您有用于动画的.gif
吗?我不知道请给我建议步骤。Hi@sambal在onPreExecute()方法中我们可以调用自定义对话框进度栏,正如您看到我的帖子一样
You should use custom dialog in onPreExecute()
Dialog mDialog = new Dialog(mContext,
android.R.style.Theme_Translucent_NoTitleBar);
mDialog.setContentView(R.layout.progressbar);
mDialog.setCancelable(false);
mDialog.show();`enter code here`
