我在我的应用中实现了对话框。但默认情况下左侧的对话框中的标题。如何在中心设置对话框标题？

这是我的代码

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);

如果您使用AlertDialog Builder，请为对话框标题创建一个布局（例如，您可以在其中居中文本），对其进行充气并将其提供给构建器。像这样：

res / layout / dialog_title.xml：

final ResponseInfo info = responseEnvelope.body.requestData.info;
System.out.println(info.accessToken);
System.out.println(info.credentialId);

爪哇：

<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"/>

如何在对话框中居中标题？
