Question

我正在尝试创建一个占用98％宽度和90％高度

的对话框片段

   @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Dialog dialog = new Dialog(getActivity());
        int width = (int)(0.98 * getResources().getDisplayMetrics().widthPixels);
        int height = (int)(0.9 * getResources().getDisplayMetrics().heightPixels);

        dialog.getWindow().setLayout(width, height);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

        View root = getActivity().getLayoutInflater().inflate(R.layout.dialog_collector_rating, null);
        getReference(root);
        dialog.setContentView(root);

        return dialog;
    }

    private void getReference(View root){

        if(mRates == null){
            mRates = new ArrayList<TopRateDataItem>();
        }

        // list
        ListView ratingList = (ListView) root.findViewById(R.id.ratingList);
        RatingAdapter adapter = new RatingAdapter();
        ratingList.setAdapter(adapter);

        // workers number
        TextView tvWorkersNum = (TextView) root.findViewById(R.id.tvWorkersNum);
        tvWorkersNum.setText(getString(R.string.dialog_collector_rating_workers, mRates.size()));

        // button
        View btnClose = root.findViewById(R.id.btnClose);
        btnClose.setOnClickListener(this);
    }

//    @Override
//    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//
//        if(mRates == null){
//            mRates = new ArrayList<TopRateDataItem>();
//        }
//
//        // Inflate view
//        View root = getActivity().getLayoutInflater().inflate(R.layout.dialog_collector_rating, null);
//
//        // list
//        ListView ratingList = (ListView) root.findViewById(R.id.ratingList);
//        RatingAdapter adapter = new RatingAdapter();
//        ratingList.setAdapter(adapter);
//
//        // workers number
//        TextView tvWorkersNum = (TextView) root.findViewById(R.id.tvWorkersNum);
//        tvWorkersNum.setText(getString(R.string.dialog_collector_rating_workers, mRates.size()));
//
//        // button
//        View btnClose = root.findViewById(R.id.btnClose);
//        btnClose.setOnClickListener(this);
//
//        return root;
//    }

布局：

        <Button

        <LinearLayout

            android:orientation="horizontal"
            android:gravity="right|center_vertical">

            <TextView
                android:id="@+id/tvWorkersNum"
                android:layout_width="0dp"
                android:layout_weight="1"
                android:layout_height="wrap_content"
                android:textStyle="bold"
                android:maxLines="1"/>

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"

                android:text="@string/dialog_collector_rating_all"/>
        </LinearLayout>

    </LinearLayout>

</LinearLayout>

我尝试使用onCreateDialog和'onCreateView'，在这两种情况下，即使尝试输入硬编码的宽度和高度，对话框也不会发生任何变化。
如何做到这一点？

覆盖窗口的大小，如下所示：

@Override
public void onResume() {

    // Store access variables for window and blank point
    Window window = getDialog().getWindow();
    Point size = new Point();

    // Store dimensions of the screen in `size`
    Display display = window.getWindowManager().getDefaultDisplay();
    display.getSize(size);

    //resize
    window.setLayout((int) (size.x *0.98), (int) (size.y *0.9));
    window.setBackgroundDrawableResource(android.R.color.transparent);
    window.setGravity(Gravity.CENTER);

    super.onResume();
}

Android Dialog片段更改大小
