ANDROID笔记:AdapterViewFlipper和ViewFlipper的简单使用

package com.example.android_flipper;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.AdapterViewFlipper;
import android.widget.Toast;

public class MainActivity extends Activity {
    int counter = 0;
    int[] images = { R.drawable.a1, R.drawable.a2, R.drawable.a3, R.drawable.a4 };
    // 监听AdapterViewFlipper
    private View.OnClickListener imageViewListener = new OnClickListener() {

        @Override
        public void onClick(View v) {
            Toast.makeText(getApplicationContext(), "image", 200).show();

        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.filppertext);
        AdapterViewFlipper flipper = (AdapterViewFlipper) findViewById(R.id.filpper);
        flipper.setAdapter(new FlipperAdapter(getApplicationContext(), images,
                imageViewListener));
        // 开始滑动
        flipper.startFlipping();

    }
}

package com.example.android_flipper;

import android.content.Context;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.AdapterViewFlipper;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;
import android.widget.Toast;

public class FlipperAdapter extends BaseAdapter {
    private int[] images;
    private Context context;
    private OnClickListener listener;
    Animation animation;

    public FlipperAdapter(Context context, int[] images,
            OnClickListener listener) {
        this.images = images;
        this.context = context;
        this.listener = listener;

    }

    public void setListener(OnClickListener listener) {
        this.listener = listener;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return images.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return images[position];
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        final ImageView imageView = new ImageView(context);
        imageView.setScaleType(ScaleType.FIT_XY);
        imageView
                .setLayoutParams(new AdapterViewFlipper.LayoutParams(480, 800));
        imageView.setImageResource(images[position]);
        // 设置显示的动画效果
        animation = AnimationUtils.loadAnimation(context, R.anim.alpha1);
        imageView.setAnimation(animation);

        imageView.setOnClickListener(listener);
        return imageView;
    }
}

<?xml version="1.0" encoding="utf-8"?>
<AdapterViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/filpper"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:flipInterval="4000"
    android:orientation="vertical" >

</AdapterViewFlipper>

注：

AdapterViewFlipper 不能直接添加监听


ViewFlipper的使用

package com.example.android_viewflipper;

import android.app.Activity;
import android.os.Bundle;
import android.view.GestureDetector;
import android.view.GestureDetector.OnGestureListener;
import android.view.MotionEvent;
import android.widget.ImageView;
import android.widget.ViewFlipper;

public class MainActivity extends Activity implements OnGestureListener {
    ViewFlipper flipper;
    GestureDetector mGestureDetector;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        flipper = (ViewFlipper) findViewById(R.id.flipper);
        ImageView imageView = new ImageView(getApplicationContext());
        imageView.setBackgroundResource(R.drawable.ic_launcher);
        flipper.addView(imageView);
        // 手势
        mGestureDetector = new GestureDetector(this);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mGestureDetector.onTouchEvent(event);
    }

    @Override
    public boolean onDown(MotionEvent e) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public void onShowPress(MotionEvent e) {
        // TODO Auto-generated method stub

    }

    @Override
    public boolean onSingleTapUp(MotionEvent e) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
            float distanceY) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public void onLongPress(MotionEvent e) {
        // TODO Auto-generated method stub

    }

    /**
     * 滑动变换图片
     */
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {
        if (e2.getX() - e1.getX() > 100) {
            flipper.showPrevious();
        } else if (e2.getX() - e1.getX() < 100) {
            flipper.showNext();
        }
        return false;
    }

}
