Question

我的应用程序中有一个包含微调器的对话框。该对话框旨在覆盖整个屏幕空间。虽然微调器只是对话框的一部分，但在选择微调器的下拉菜单时，下拉菜单覆盖了整个屏幕空间。请参考下面的图像以获得对话框参考：

现在点击微调按钮后，下拉列表如下图所示：

正如您所看到的，它覆盖了整个屏幕，因为我希望它的宽度限制在微调器宽度。下面我发布了微调器的代码：

对话框代码：

final Dialog dlg_dialog = new Dialog(myContext, R.style.Theme_Dialog);
                // dialog.setCancelable(false);
                dlg_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
                Window window = dlg_dialog.getWindow();
                if (window == null) return;
                WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
                lp.copyFrom(dlg_dialog.getWindow().getAttributes());
                lp.width = WindowManager.LayoutParams.FILL_PARENT;
                lp.height = WindowManager.LayoutParams.MATCH_PARENT;
                lp.gravity = Gravity.CENTER;
                dlg_dialog.getWindow().setAttributes(lp);
                //dialog.setContentView(R.layout.new_field_quote_entry_dialog);
                dlg_dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
                dlg_dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
                dlg_dialog.setContentView(R.layout.new_field_quote_entry_dialog);
                //  final Spinner spnr_spinnerSelectMarket = (Spinner)dlg_dialog.findViewById(R.id.spinnerSelectMarket);
                TextView txtv_selectCompetitorDropDown = (TextView) dlg_dialog.findViewById(R.id.spinnerSelectCompetitorDropDown);
                final Spinner spnr_spinnerSelectCompetitor = (Spinner) dlg_dialog.findViewById(R.id.spinnerSelectCompetitor);
                spnr_spinnerSelectCompetitor.setClickable(false);
                spnr_spinnerSelectCompetitor.setEnabled(false);

style.Dialog：

 <style name="Theme_Dialog" parent="android:Theme.Dialog">
    <item name="android:windowMinWidthMajor">100%</item>
    <item name="android:windowAnimationStyle">@null</item>
    <item name="android:windowMinWidthMinor">100%</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:windowIsFloating">false</item>

现在显示下拉列表，使用以下代码：

  CustomSpinnerAdapter customSpinnerAdapterCompetitor = new CustomSpinnerAdapter(myContext,
                                    R.layout.spinner_row, alst_competitor, "Select Competitor");
                            competitor_spinner.setAdapter(customSpinnerAdapterCompetitor);

现在为CustomSpinnerAdapter：

public class CustomSpinnerAdapter extends ArrayAdapter<String> {

Context context;
ArrayList<String> objects;
String firstElement;
boolean isFirstTime;

public CustomSpinnerAdapter(Context context, int textViewResourceId, ArrayList<String> objects, String defaultText) {
    super(context, textViewResourceId, objects);
    this.context = context;
    this.objects = objects;
    this.isFirstTime = true;
    setDefaultText(defaultText);
}

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
    if(isFirstTime) {
        objects.set(0, firstElement);
        isFirstTime = false;
    }
    return getCustomDropdownView(position, convertView, parent);
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    notifyDataSetChanged();
    return getCustomView(position, convertView, parent);
}

public void setDefaultText(String defaultText) {
    this.firstElement = objects.get(0);
    objects.set(0,defaultText);
}

public View getCustomView(int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View row = inflater.inflate(R.layout.spinner_row, parent, false);
    TextView label = (TextView) row.findViewById(R.id.spinnerText);
    label.setText(objects.get(position));

    return row;
}
public View getCustomDropdownView(int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View row = inflater.inflate(R.layout.simple_spinner_dropdown_item, parent, false);
    CheckedTextView label = (CheckedTextView) row.findViewById(R.id.text1);
    label.setText(objects.get(position));


    return row;
}

}

/Just remove the below lines of code/

            WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
            lp.copyFrom(dlg_dialog.getWindow().getAttributes());
            lp.width = WindowManager.LayoutParams.FILL_PARENT;
            lp.height = WindowManager.LayoutParams.MATCH_PARENT;
            lp.gravity = Gravity.CENTER;
            dlg_dialog.getWindow().setAttributes(lp);

旋转下拉覆盖整个屏幕
