Android - Handler is abstract, cannot be instantiated

Android - Handler is abstract, cannot be instantiated.

Handler is abstract, cannot be instantiated.

Android使用Handler进行实例化(new)时, 如: private Handler handler = new Handler();

会报错"Handler is abstract, cannot be instantiated.", 提示使用, 其他实例化方式.

原因: 导入(import)库发生错误, 使用Android的句柄(handler)库, 不是java的句柄库;

使用"import android.os.Handler;" 代替 "import java.util.logging.Handler;"

即可, Handler的使用方法:

private Handler handler = new Handler();
...
handler.post(new Runnable() {
   @Override
   public void run() {
        addNewQuake(quake);
   }
});
