Android标题栏中添加返回按钮功能-创新互联

标题栏中的返回按钮在实际使用中用的比较多，今天就来讲讲我在项目开发中的使用经历，话不多说，还是直接上源码，上源码是最给力的。

一、 编写自定义类

public class CustomTitle {  
  private static Activity mActivity;  
  public static void getCustomTitle(Activity activity, String title) { 
   mActivity = activity; 
    mActivity.requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 
   mActivity.setContentView(R.layout.custom_title); 
    mActivity.getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, 
        R.layout.custom_title);     
    TextView textView = (TextView) activity.findViewById(R.id.head_center_text);  
    textView.setText(title);  
   Button titleBackBtn = (Button) activity.findViewById(R.id.TitleBackBtn);  
    titleBackBtn.setOnClickListener(new OnClickListener() {  
      public void onClick(View v) {  
       Log.d("Title back","key down"); 
         
        mActivity.finish(); 
      }  
    });  
  } 
}
