onSwipe（INT方向）不工作 [英] onSwipe(int direction) not working

问题描述

我不能覆盖onSwipe（）方法。错误是类型的方法onSwipe（INT）将必须覆盖或实现超法。谁能告诉我我做错了什么？我想用滑动手势活动之间进行导航。是否有任何其他方式做到这一点？如果是的话请解释。我不得不进口更多的包呢？

解决方案

您的活动应该实现SimpleGestureListener才能够收到手势事件。

 公共类添加扩展活动实现OnGestureListener
 

I can't override the onSwipe() method. The error is "The method onSwipe(int) of type Adds must override or implement a supertype method". Can anyone tell me what I did wrong?. I want to navigate between activities using swipe gesture. Is there any other way to do it? If so please explain. Do I have to import any more packages?

package com.mahavega.qcdemo;

import com.mahavega.qcdemo.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.widget.TextView;

public class Adds extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ads);
        TextView tv1 = (TextView) findViewById(R.id.textView1);
        tv1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                startActivity(new Intent(Adds.this, Ads2.class));
            }
        });
        ImageView im1 = (ImageView) findViewById(R.id.imageView1);
        im1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                startActivity(new Intent(Adds.this, Real.class));
            }
        });
    }
    @Override
    public void onSwipe(int direction) {
        Intent intent = new Intent();

        switch (direction) {
        case SimpleGestureFilter.SWIPE_RIGHT:
            intent.setClass(this, Ads2.class);
            break;

        case SimpleGestureFilter.SWIPE_LEFT:
            intent.setClass(this, Ads3.class);
            break;
        }

        startActivity(intent);
    }
}

解决方案

your activity should implement SimpleGestureListener to be able to recieve gesture events.

public class Adds extends Activity implements OnGestureListener
