android - 如何为对话框dialogfragment设置长标题？

Question

我想要带有书名的标题对话框。问题出在长标题上，似乎默认标题对话框试图修剪超长文本以适应对话框宽度

所以我想出了通过这段代码删除默认标题的解决方案

setStyle(STYLE_NO_TITLE, 0);

用 textview 小部件替换默认值。这是我的自定义对话框 xml

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

    <TextView
        android:id="@+id/dialog_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

但是它只是弄乱了对话框布局

那么任何人都可以更好地处理这个问题吗？谢谢

Answer 1

You can use google to set custom view to a dialog

but don't forget to dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); :)

Answer 2

So in your DialogFragments onCreate you setStyle:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NO_TITLE, R.style.Theme_Dialog);
}

You then use your own very custom xml layout to create the dialog in oncreateview().
