删除dialogfragment中的白色背景 [英] remove white background in dialogfragment

问题描述

这是我叫DialogFragment的方式:

Here's how I called my DialogFragment:

DialogSelectAccount myDiag=new DialogSelectAccount();
myDiag.show(ft,"Diag" );

这是(部分地)创建我的DialogFragment的方式:

Here's how (partially) my DialogFragment is created:

public class DialogSelectAccount extends DialogFragment {
public DialogSelectAccount() {

    }

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

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.dialog_select_account, container, false);
tvMessage = (TextView) rootView.findViewById(R.id.tvMessage);
        btnAccountPublic = (Button) rootView.findViewById(R.id.btnAccountPublic);
        btnAccountEnterprise = (Button) rootView.findViewById(R.id.btnAccountEnterprise);
        tvMessage.setText(message);
        btnAccountPublic.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Login.setAccountType = 2;
                dismiss();
            }
        });
        btnAccountEnterprise.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Login.setAccountType = 1;
                dismiss();
            }
        });
        return rootView;
    }

这是我的DialogSelectAccount的xml

and here's the xml for my DialogSelectAccount

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#ff26b4e9"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/tvMessage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:textColor="@android:color/black"
        android:textSize="15dp"
        android:textAlignment="center"
        android:gravity="center_horizontal"
        android:background="#ff26b4e9"
        android:autoText="true">
    </TextView>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#ff26b4e9"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/btnAccountPublic"
            android:layout_width="150dp"
            android:layout_height="wrap_content"
            android:clickable="true"
            android:text="@string/accountPub"
            android:textColor="#ffffffff"
            android:background = "@drawable/roundedbutton" />

        <Button
            android:id="@+id/btnAccountEnterprise"
            android:layout_width="150dp"
            android:layout_height="wrap_content"
            android:layout_marginLeft="5dp"
            android:clickable="true"
            android:text="@string/accountEnt"
            android:textColor="#ffffffff"
            android:background = "@drawable/roundedbutton" />
    </LinearLayout>

</LinearLayout>

问题在于总是显示出令人讨厌的白色背景，如下所示.如何删除它?

the problem is there's always an innoying white background displayed, as shown below. How do I remove it?

推荐答案

在您的DialogFragment的onCreateView()中，替换

View rootView = inflater.inflate(R.layout.dialog_select_account, container, false);

使用

View rootView = inflater.inflate(R.layout.dialog_select_account, container);

此外，将其添加到onViewCreated():

getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
setStyle(DialogFragment.STYLE_NO_FRAME, android.R.style.Theme);

并在XML的最外层LinearLayout中进行更改

and in the outermost LinearLayout of the XML, change

android:layout_width="fill_parent"
android:layout_height="fill_parent"

到

android:layout_height="wrap_content"
android:layout_width="wrap_content"

尝试一下.这应该起作用.

Try this. This should work.
