Question

I have a number of dialogs in a application where a custom view is used. Prior to Android 4 the height and width of these dialogs are adapting as I would expect according to the content. In an Andorid 4 emulator this behavior has changed. It looks like the width will stretch to accomodate content but it has a minimum size below which it will not go. I can make a dialog wider but for narrow content the dialog box will not reduce as I would expect. My content is therefore showing in the left side of an overwide dialog box. All works perfectly on 3.0. I have tried:

dialog.setContentView(R.layout.help_dialog);
dialog.getWindow().setLayout(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

这没有任何效果。标题的内容也不迫使方言延伸。任何想法都受到高度赞赏。

Answer 1

我也存在同样的问题,认为:

final Dialog help = new Dialog(this);
WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
lp.copyFrom(help.getWindow().getAttributes());

lp.width = (int) (width);
lp.height = (int) (height);

help.show();
help.getWindow().setAttributes(lp);

Answer 2

我发现,你可以将方言的比值定为可提的xml。

    Dialog dialog = new Dialog(this);

    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.getWindow().setBackgroundDrawableResource(r.drawable.your_drawable);
    dialog.getWindow().setContentView(R.layout.your_custom_dialog_layout);
    dialog.getWindow().getAttributes().width = LayoutParams.FILL_PARENT;
    dialog.show();

审视一下可以选择的粗鲁。

<?xml version="1.0" encoding="utf-8"?>
<layer-list>
    <item
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:left="70dp"
        android:right="70dp">
        <shape android:shape="rectangle" >
            <solid android:color="@color/white" />
            <corners android:radius="4dp" />
            <padding
                android:bottom="70dip"
                android:left="70dip"
                android:right="70dip"
                android:top="70dip" />
        </shape>
    </item>
</layer-list>

By setting the item android:right/left it margins the drawable. With the shape padding you make sure fields wihtin the custom_dialog_layout do not exceed the width of the dialog background.

我希望这能帮助你。
