android自定义class类写监听接口

public class MyClass {

    public MyClass(Context context) {
		mContext = context;
		
	}


    OnLoadFinishedListener onloadfinishedlistener;
    // 提供接口
	public interface OnLoadFinishedListener {

		void onLoadFinish();

		void onLoadFailed();
	}

	public void setOnDataFinishedListener(OnLoadFinishedListener onloadfinishedlistener) {
		this.onloadfinishedlistener = onloadfinishedlistener;
	}

    //将上面代码复制到你的类中，在需要的地方插入加载完毕，或者加载失败的方法即可
    //onloadfinishedlistener.onLoadFinish
    //onloadfinishedlistener.onLoadFailed

    

}

调用方法

//主线程中异步回调方法
MyClass c =new MyClass(this);
c.setOnDataFinishedListener(new OnLoadFinishedListener() {
			
			@Override
			public void onLoadFinish() {
				// 加载完毕
				
				
			}
			
			@Override
			public void onLoadFailed() {
				// 加载失败
				
			}
		});
