Question

我需要在我的应用中显示对话框，如下所示：

Desired output

早些时候我使用的是Popup window，因此它显示正确。但是，我稍后将其更改为DialogFragment，因为与此类似的其他对话框将具有ListViews and Tabs。因此，使用DialogFragment会更灵活。

将其更改为DialogFragment后，显示如下： Present output

这是我的Dialog Fragment代码：

public class AddTransactionDialogFragment extends DialogFragment {

private final String TAG = "AddTransactionDialog";
private View anchorView; // Anchor view here in Dollar button

private int dialogHeight, dialogWidth; // Width and height are the size this
                                        // dialog should have

private View contentView;

public AddTransactionDialogFragment() {
}

public AddTransactionDialogFragment(View anchorView, int dialogHeight,
        int dialogWidth) {
    this.anchorView = anchorView;
    this.dialogHeight = dialogHeight;
    this.dialogWidth = dialogWidth;
    Log.e(TAG, "Dialog width: " + dialogWidth + " Dialog height: "
            + dialogHeight);
}

public static AddTransactionDialogFragment newInstance(
        FriendsDAO mFriendsDao) {
    AddTransactionDialogFragment fragment = new AddTransactionDialogFragment();

    Bundle args = new Bundle();
    args.putParcelable("friendsDao", mFriendsDao);
    fragment.setArguments(args);
    return fragment;
}

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

    setStyle(STYLE_NO_FRAME, R.style.AddTransactionDialog);
}

@Override
public void onStart() {
    super.onStart();

    Window window = getDialog().getWindow();
    WindowManager.LayoutParams params = window.getAttributes();
    params.dimAmount = 0.2f;
    window.setAttributes(params);

    window.setBackgroundDrawableResource(android.R.color.transparent);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    contentView = inflater.inflate(R.layout.add_transaction_popup,
            container, false);
    setDialogPosition();
    return contentView;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
}

private void setDialogPosition() {
    if (anchorView == null) {
        return;
    }
    int[] location = new int[2];
    anchorView.getLocationOnScreen(location);
    int anchorViewX = location[0];
    int anchorViewY = location[1];

    Log.e(TAG, "AnchorViewX: " + anchorViewX + " AnchorViewY: "
            + anchorViewY);
    Window window = getDialog().getWindow();

    window.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL);

    window.setBackgroundDrawable(new ColorDrawable(
            android.graphics.Color.TRANSPARENT));

    WindowManager.LayoutParams params = window.getAttributes();
    params.copyFrom(window.getAttributes());

    Log.e("AddTransactionDialog",
            "Anchor view width: " + anchorView.getWidth());
    Log.e("AddTransactionDialog",
            "Anchor view height: " + anchorView.getHeight());

    params.x = anchorViewX - anchorView.getWidth();
    params.y = anchorViewY - anchorView.getHeight();
    params.height = dialogHeight;
    params.width = dialogWidth;
    window.setAttributes(params);
}

public int dpToPx(float valueInDp) {
    DisplayMetrics metrics = getActivity().getResources()
            .getDisplayMetrics();
    return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
            valueInDp, metrics);
}
}

如何使用对话框片段获得所需的对话框（如第一张图片所示）？

Answer 1

对于内容视图，您正在设置DialogFragment，您是否尝试将layout_height设置为wrap_content？

这里的问题是layout_height是match_parent。
