如何在android中动态设置自定义标题栏TextView值? [英] how to set custom title bar TextView Value dynamically in android?

问题描述

朋友，

我使用以下带有代码的 titlebar.xml 文件创建了自定义标题栏

i have created custom title bar using following titlebar.xml file with code

<?xml version="1.0" encoding="utf-8"?> 
<TextView 
  xmlns:android="http://schemas.android.com/apk/res/android" 
  android:id="@+id/myTitle" 
  android:text="This is my new title" 
  android:layout_width="fill_parent" 
  android:layout_height="fill_parent" 
  android:textColor="@color/titletextcolor"
  android:layout_marginLeft="25px"
   android:paddingTop="3px" 
   /> 

和用于在每个活动上显示自定义标题栏的 java 代码.

and java code to display custom title bar on each activity.

@Override
    public void onCreate(Bundle savedInstanceState)
    {
requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 
        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.mytitle);

super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


}

现在我想在每个活动中动态设置 textview 值，谁能指导我如何实现这一点?

now i want to set textview value dynamically in each activity can any one guide me how can i achieve this?

在这里使用 findviewbyid 我没有得到那个 textview 的参考来设置值，因为主布局不包含任何具有此类名称的文本框，但包含 mytitle.

using findviewbyid here i dont get reference of that textview to set value because main layout does not contains any textbox with such a name but mytitle.

任何帮助都会得到帮助.

any help would be appriciated.

推荐答案

自定义标题的设置方法如下:

This is the way to set the custom title:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    final boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);

    setContentView(R.layout.main);

    if ( customTitleSupported ) {
        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.mytitle);
    }

    final TextView myTitleText = (TextView) findViewById(R.id.myTitle);
    if ( myTitleText != null ) {
        myTitleText.setText("========= NEW TITLE ==========");
        myTitleText.setBackgroundColor(Color.GREEN);
    }


}
