我想显示一个比屏幕宽度宽的底部对话框.

例如,Nexus 9上的Google Play音乐分享选项.

你知道如何实现这个目标吗？

现在我刚刚尝试减少工作表内容的宽度,但背景仍然在屏幕宽度并显示白色背景.

一些代码:

的build.gradle

compile 'com.android.support:design:23.3.0'

主要活动

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...

    mBottomSheetDialog = new BottomSheetDialog(this);
    mBottomSheetDialog.setContentView(R.layout.sheet_test);
    mBottomSheetDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
        @Override
        public void onDismiss(DialogInterface dialog) {
            mBottomSheetDialog = null;
        }
    });
    mBottomSheetDialog.show();
}

sheet_test

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="100dp"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            style="@style/TextAppearance.AppCompat.Body1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="16dp"
            android:text="Some Text"
            android:textColor="@color/colorPrimary" />

        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="#ddd" />

        <TextView
            style="@style/TextAppearance.AppCompat.Body1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_margin="16dp"
            android:text="Some Text" />

        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="#ddd" />

    </LinearLayout> …

以下是我调用DialogFragment的方法:

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

这是(部分)我的DialogFragment的创建方式:

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 …
