Android 12设备上的Android对话裁剪问题

Question

我们在市场上有许多应用程序使用对话fragment（AppCompatdialogfragment版本）。我们发现，在某些设备，三星选项卡S7上，对话框被截断，以免显示底部的信息和动作按钮。我尝试过的任何事情都不会以在所有设备上保持一致的方式解决此问题。我制作了一个简单的布局和代码以演示。该代码按照截断的图像插入到实时应用程序中时，在新创建的测试应用中，它正常在同一设备上显示！所有主题，清单设置看起来都相似。我已经花了很多天的时间了，因此任何建议都将不胜感激。

public class DlgTest extends AppCompatDialogFragment {



    static DlgTest newInstance() {

        return new DlgTest();
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setStyle(DialogFragment.STYLE_NO_TITLE, R.style.DialogStyle);

    }

    @Override
    public void onStart() {
        super.onStart();
        int targetWidth = 1000;
        int targetHeight = 0;

        // check if specific size setting is required
        if (targetWidth != 0 || targetHeight != 0) {

            var dialog = getDialog();
            if (dialog == null) return;
            var window = dialog.getWindow();

            if (targetHeight > 0) lp.height = targetHeight;

Answer 1

我认为问题在于onstart（）方法。
您可以尝试像以下那样改变吗？

    @Override
    public void onStart() {
        super.onStart();
        Window win = getDialog().getWindow();
        if (win == null)
            return;

        DisplayMetrics dm = new DisplayMetrics();
        ((Activity) mContext).getWindowManager().getDefaultDisplay().getMetrics(dm);
        WindowManager.LayoutParams params = win.getAttributes();
        int contextRect = getContextRect((Activity) mContext);

        params.gravity = Gravity.CENTER; //you can change Gravity in here
        params.width = ViewGroup.LayoutParams.MATCH_PARENT; //you can change width in here
        int screenHeight = contextRect == 0 ? ViewGroup.LayoutParams.MATCH_PARENT : contextRect;
        params.height = screenHeight;
        win.setAttributes(params);
    }

    private int getContextRect(Activity activity) {
        Rect outRect = new Rect();
        activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(outRect);
        return outRect.height();
    }

这可能会有所帮助

   override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setStyle(STYLE_NORMAL, R.style.FullscreenDialogStyle)
    dialog?.let {
        it.window?.setLayout(
            WindowManager.LayoutParams.MATCH_PARENT,
            WindowManager.LayoutParams.MATCH_PARENT
        )
    }
}

    <style name="FullscreenDialogStyle">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
</style>

三星的更新解决了这个问题！我不知道是什么基本问题是什么，但不再是一个问题。感谢所有对此思考的人。
