如何使对话框中的标题居中？

Question

我已经在我的应用程序中实现了对话框。但对话框中的标题默认在左侧。如何使对话框标题居中？

这是我的代码

final Dialog dialog = new Dialog(getActivity());
dialog.setContentView(R.layout.contact_query);
dialog.setTitle("Query Form");

Answer 1

你可以试试这个：

// Creating the AlertDialog with a custom xml layout (you can still use the default Android version)
AlertDialog.Builder builder = new AlertDialog.Builder(this);
LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.viewname, null);
builder.setView(view);

TextView title = new TextView(this);
// You Can Customise your Title here 
title.setText("Custom Centered Title");
title.setBackgroundColor(Color.DKGRAY);
title.setPadding(10, 10, 10, 10);
title.setGravity(Gravity.CENTER);
title.setTextColor(Color.WHITE);
title.setTextSize(20);

builder.setCustomTitle(title);

*试试这个*

    Dialog dialog = new Dialog(this);

    dialog.setContentView(R.layout.yourlayout);

    TextView titleView = (TextView)dialog.findViewById(android.R.id.title);

    titleView.setGravity(Gravity.CENTER);

如果您使用 AlertDialog 构建器，请为您的对话框标题创建一个布局（例如，您可以在其中将文本居中），将其膨胀并将其提供给构建器。像这样：

res/layout/dialog_title.xml：

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="@color/colorPrimaryDark_rc"
  android:textSize="22sp"
  android:gravity="center"
  android:textColor="@color/textColorPrimaryDark"
  android:padding="10dp"/>

Java：

public Dialog onCreateDialog(Bundle savedInstanceState) {

    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(act);

    LayoutInflater layoutInflater = act.getLayoutInflater();
    View customView = layoutInflater.inflate(R.layout.l_df_episode_details, null);
    alertDialogBuilder.setView(customView);

    TextView tv = (TextView) layoutInflater.inflate(R.layout.dialog_title, null);
    tv.setText("YOUR TITLE");
    alertDialogBuilder.setCustomTitle(tv); 

    ......

    alertDialog = alertDialogBuilder.create();
    return alertDialog;
}
