Why my dialog layout wont spread correctly?

问题

In my layout (its layout for custom dialog class), whenever I set my layout attributes like this :

android:layout_width="match_parent"
android:layout_height="match_parent"

I don't see a layout that spreads all over the screen, I see it like this:

As you can see, the dialog is very small and weird looking although I am using match_parent, the weird part is that whenever I use fixed size I see it normally.

For example - for those attributes:

android:layout_width="300dp"
android:layout_height="300dp"

I see it like this:

Do you have any idea why this is happening or if I am doing something wrong? I don't want to use a fixed size because that will make my layout non-responsive.

Here is my layout file :

回答1:

You can achieve what you want with setting LayoutParams of Dialog

Here is the code

Window window = yourDialog.getWindow();
if (window != null) {
    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
    lp.copyFrom(window.getAttributes());
    //This makes the dialog take up the full width
    lp.width = WindowManager.LayoutParams.MATCH_PARENT;
    lp.height = WindowManager.LayoutParams.MATCH_PARENT;
    window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    window.setAttributes(lp);
}

回答2:

Try this way

Window window = yourDialog.getWindow();
window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
window.setGravity(Gravity.CENTER);
yourDialog.show();

回答3:

Please add dynamic Width and Height to your Dialog. You can use LayoutParams for that.

Dialog dialog = new Dialog(context);
dialog.show();
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
dialog.setCancelable(true);
Window window = dialog.getWindow();
window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

Please you this code: Set programmatically ConstraintLayout height and width
