每当我想在我的应用程序中显示进度条时,我调用此方法,此方法将ProgressBar添加到我的布局中.
问题：我想在Dialog上显示此进度条,但Dialog始终显示在上面.这种情况可以做些什么？
public static void showProgressBar(@NonNull final Activity activity) {
try {
if (activity == null) {
LogManager.printstacktrace(new NullActivityException());
return;
}
View view = activity.findViewById(android.R.id.content);
if (view == null) {
LogManager.printstacktrace(new NullPointerException("content view is null"));
return;
}
View rootView = activity.findViewById(android.R.id.content).getRootView();
if (rootView == null || !(rootView instanceof ViewGroup)) {
LogManager.printstacktrace(new NullPointerException("rootView is null or not an instance of ViewGroup"));
return;
}
final ViewGroup layout = (ViewGroup) rootView;
final ProgressBar progressBar = new ProgressBar(activity);
progressBar.setIndeterminate(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Drawable wrapDrawable = DrawableCompat.wrap(progressBar.getIndeterminateDrawable());
DrawableCompat.setTint(wrapDrawable,ContextCompat.getColor(activity,R.color.colorAccent));
progressBar.setIndeterminateDrawable(DrawableCompat.unwrap(wrapDrawable));
}
RelativeLayout.LayoutParams params = new
RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT,RelativeLayout.LayoutParams.MATCH_PARENT);
final RelativeLayout rl = new RelativeLayout(activity);
rl.setBackgroundColor(ActivityCompat.getColor(activity,R.color.tc_hint_grey_alpha));
rl.setClickable(true);
rl.setTag("#$UniqueProgressBar");
ViewGroup.LayoutParams params2 = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,120);
rl.setGravity(Gravity.CENTER);
rl.addView(progressBar,params2);
LogManager.i("ProgressBar","ProgressUtils.showProgressBar->called");
layout.addView(rl,params);
mRunnable = new Runnable() {
@Override
public void run() {
LogManager.i("ProgressBar","ProgressUtils.showProgressBar->120 secs timeout");
hideProgressBar(activity);
}
};
mHandler = new Handler();
mHandler.postDelayed(mRunnable,120000);
LogManager.i("ProgressBar","Added");
} catch (Exception e) {
LogManager.printstacktrace(e);
}
}
解决方法
尝试这样的东西,它应该全局工作：
public static void showProgressBar(@NonNull final Activity activity) {
try {
if (activity == null) {
LogManager.printstacktrace(new NullActivityException());
return;
}
final WindowManager wm = (WindowManager) activity.getApplicationContext().getSystemService(Activity.WINDOW_SERVICE);
final ProgressBar progressBar = new ProgressBar(activity);
progressBar.setIndeterminate(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
Drawable wrapDrawable = DrawableCompat.wrap(progressBar.getIndeterminateDrawable());
DrawableCompat.setTint(wrapDrawable,R.color.colorAccent));
progressBar.setIndeterminateDrawable(DrawableCompat.unwrap(wrapDrawable));
}
WindowManager.LayoutParams windowLayoutParams = new WindowManager.LayoutParams();
windowLayoutParams.gravity = Gravity.CENTER;
windowLayoutParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_PANEL;
windowLayoutParams.token = activity.getwindow().getDecorView().getwindowToken();
windowLayoutParams.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
windowLayoutParams.height = LayoutParams.MATCH_PARENT;
windowLayoutParams.width = LayoutParams.MATCH_PARENT;
wm.addView(progressBar,windowLayoutParams);
LogManager.i("ProgressBar","Added");
} catch (Exception e) {
LogManager.printstacktrace(e);
}
}
