DialogFragment是全屏的。如何让它变得小巧

Question

我有这个DialogFragment。当我显示它时，它变成全屏，我的意思是它与当前屏幕重叠。如何让它变得像AlertDialog一样小？

我猜是因为RelativeLayout的缘故，所以我把LinearLayout包装在RelativeLayout之外，但什么也没改变。

public class LoginDialogFragment extends DialogFragment {

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

@Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
        final Bundle savedInstanceState) {
    final View v = inflater.inflate(R.layout.login_dialog, container, false);
    final EditText emailEditText = (EditText)v.findViewById(R.id.emailEditText);
    final EditText passwordEditText = (EditText)v.findViewById(R.id.passwordEditText);
    final Button loginButton = (Button)v.findViewById(R.id.loginButton);
    loginButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(final View v) {
                checkLogin(emailEditText.getText().toString(), passwordEditText.getText().toString());
            }
        });
    return v;
}
}

布局

    </RelativeLayout>

</LinearLayout>

Answer 1

在onCreate()中调用setStyle(STYLE_NORMAL, android.R.style.Theme_Dialog);而不是setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme);。有帮助吗？
