对话框自定义标题以匹配非自定义标题

Question

我的一个对话框有一个非自定义标题：

NameDialog.java

public class NameDialog extends DialogFragment {
    @Override
    @NonNull
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        LayoutInflater inflater = getActivity().getLayoutInflater();
        return builder.setTitle(R.string.name)
                .setView(inflater.inflate(R.layout.name_dialog, null))
                .setPositiveButton(R.string.next, null)
                .create();
    }
}

name_dialog.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">

    <EditText
        android:id="@+id/name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:ems="10"
        android:inputType="textPersonName"
        android:textAppearance="?android:attr/textAppearanceLarge"/>
</LinearLayout>

                .setView(inflater.inflate(R.layout.players_dialog, null))
                .setPositiveButton(R.string.start_game, null)
                .create();
    }
}

              tools:context=".PlayersDialog">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/title"
        android:text="@string/players"
        android:layout_centerVertical="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:layout_marginLeft="5dp"/>

    <android.support.v7.app.MediaRouteButton

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_centerVertical="true"
        android:mediaRouteTypes="user"
        android:visibility="gone"/>

</RelativeLayout>

我只希望两个对话框的格式一致。

在您的 players_title_dialog.xml 文件中，将播放器 textView 替换为以下内容

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/title"
        android:text="@string/players"
        android:layout_centerVertical="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="#3db6e3"
        android:layout_marginLeft="10dp"/>

并且可能是字体大小可以减少 1dp 并且可以在您的列表中添加 3px 的填充
