对话框片段不占据整个屏幕

Question

我正在打开对话框片段。但是，它不会占据整个屏幕。我的意思是它留下了一些space。

下面是我的代码：

    public class MyDialogFragment extends DialogFragment implements View.OnClickListener{
        private Context context = getActivity();

        private ImageView imageViewCancel;
        private TextView textViewTitle;
        private View view;

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            view = inflater.inflate(R.layout.layoutfile, container, false);

            getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);

            textViewTitle = (TextView) view.findViewById(R.id.textView_Screen_Title);
            setHeader("Some title");
            imageViewCancel = (ImageView) view.findViewById(R.id.imageView_Cancel);
            imageViewCancel.setOnClickListener(this);


            //to hide keyboard when showing dialog fragment
            getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

            return view;
        }

        private void setHeader(String screenTitle) {
            textViewTitle.setText(screenTitle);
        }

        @Override
        public void onClick(View view) {
            switch (view.getId()) {
                case R.id.imageView_Cancel :
                    dismiss();
                    break;
            }
        }

        @Override
        public void onStart() {
            super.onStart();
getDialog().getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
        }
    }

参考快照

我想全屏打开，这样背景透明就看不到了。 WindowManager.LayoutParams.MATCH_PARENT 和 ViewGroup.LayoutParams.MATCH_PARENT 也试过了，但没有任何效果。

Answer 1

为 Dialog

创建自定义样式

<style name="CustomDialog" parent="AppTheme" >
  <item name="android:windowNoTitle">true</item>
  <item name="android:windowFullscreen">true</item>
  <item name="android:windowIsFloating">true</item>
  <item name="android:windowCloseOnTouchOutside">true</item>
</style>

然后在对话框片段中使用该样式

@Override public void onCreate(@Nullable Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setStyle(DialogFragment.STYLE_NORMAL, R.style.CustomDialog);
}

@Override public void onStart() {
  super.onStart();
  getDialog().getWindow()
    .setLayout(WindowManager.LayoutParams.MATCH_PARENT,
        WindowManager.LayoutParams.MATCH_PARENT);
}

SampleDialogFragment sampleDialogFragment = new SampleDialogFragment();
SampleDialogFragment.show(getActivity().getSupportFragmentManager(), "sometag");

Answer 2

试试这个：在 styles.xml

中添加

 <style name="MY.DIALOG" parent="android:Theme" >
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowIsFloating">false</item>
</style>

并在您的 DialogFragment 中设置此样式：

 @Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NORMAL, R.style.MY_DIALOG);
}

对话框片段的背景会显示为黑色，请根据需要进行更改。
