我想要一个带圆角的Dialog
,但是当看到Dialog
时,在角落下方会看到一个矩形,如下所示:
我使用自定义dialog
构建DialogFragment
:
public class MyDialogFragment extends DialogFragment{
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.playdialog, null));
return builder.create();
}
}
对话框布局(playdialog)具有以下可绘制的背景:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<solid
android:color="#AAAAAAAA" />
<stroke
android:width="2dp"
android:color="#FF000000" />
<corners android:radius="20dp" />
</shape>
正如我所说,我将此drawable设置为背景:
android:background="@drawable/dialog_background"
我不希望看到那个矩形。我该怎么办?
在this帖子中,用户遇到了同样的问题。我试图使用适合他的解决方案,但它对我不起作用。我像这样修改了DialogFragment
:
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.playdialog, null));
Dialog d = builder.create();
d.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
return d;
}
结果完全一样。如何删除该矩形?
谢谢!

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="@color/text_highlight" />
<stroke
android:width="5dp"
android:color="@color/text_highlight" />
<corners android:radius="12dp" />
<stroke
android:width="1dp"
android:color="@android:color/transparent" />
</shape>
将以下行添加到对话框中:
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
// This is line that does all the magic
dialog.getWindow().setBackgroundDrawableResource(
R.drawable.dialog_rounded);

尝试将DialogFragment
的样式设置为Theme_Translucent.
setStyle(STYLE_NO_FRAME, android.R.style.Theme_Translucent);
它对我有用。

我在代码中为对话框设置了透明背景。 试试这个:
@Override
public void onStart() {
// TODO Auto-generated method stub
super.onStart();
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(0x00ffffff));
}

添加
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
到MyDialogFragment的onCreateView()
方法
