Android使用ViewFlipper实现图片切换功能

 package com.example.android21_zhangkai_gesture; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import android.view.GestureDetector; import android.view.MotionEvent; import android.widget.ImageView; import android.widget.Toast; import android.widget.ViewFlipper; public class MainActivity extends AppCompatActivity { private ViewFlipper vf_main_image; private int images[]={R.mipmap.ic_launcher,R.mipmap.ic_launcher_round}; private GestureDetector gd; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); vf_main_image = (ViewFlipper) findViewById(R.id.vf_main_image); for (int i = 0; i 200){ Toast.makeText(MainActivity.this, "右滑,上一张", Toast.LENGTH_SHORT).show(); vf_main_image.showPrevious();//上一张的方法 //动画为当前图片从右出去，新图从左进来 vf_main_image.setInAnimation(MainActivity.this,R.anim.left_in);//设置进来的动画 vf_main_image.setOutAnimation(MainActivity.this,R.anim.right_out);//设置出去的动画 }else if(e1.getX()-e2.getX()>200){ Toast.makeText(MainActivity.this, "左滑,下一张", Toast.LENGTH_SHORT).show(); vf_main_image.showNext(); //动画为当前图片从左出去，新图从右进来 vf_main_image.setInAnimation(MainActivity.this,R.anim.right_in); vf_main_image.setOutAnimation(MainActivity.this,R.anim.left_out); } return false; } }); } //给当前Activity设置触摸事件监听方法 @Override public boolean onTouchEvent(MotionEvent event) { return gd.onTouchEvent(event); } }
