在布局中加入一个RollPagerView（图片轮播的控件）和KenBurnsView控件（图片自动缩放的控件）注意：*不要忘记写读写权限： <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> *在build.gradle(Module:app)中编写: //图片轮播的控件 compile 'com.jude:rollviewpager:1.3.4' //图片自动缩放的控件 compile 'com.flaviofaria:kenburnsview:1.0.7' 程序代码： package com.example.administrator.jreduch08; import android.graphics.Color; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import com.flaviofaria.kenburnsview.KenBurnsView; import com.jude.rollviewpager.OnItemClickListener; import com.jude.rollviewpager.RollPagerView; import com.jude.rollviewpager.adapter.StaticPagerAdapter; import com.jude.rollviewpager.hintview.ColorPointHintView; public class RollPagerViewActivity extends AppCompatActivity { private RollPagerView rollPagerView; private KenBurnsView kenBurnsView; private int[] imgs={ R.mipmap.a1, R.mipmap.a2, R.mipmap.a3, }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_first); rollPagerView=(RollPagerView)findViewById(R.id.roll_view_pager); kenBurnsView=(KenBurnsView)findViewById(R.id.image); //设置播放间隔 rollPagerView.setPlayDelay(3000); //设置透明度 rollPagerView.setAnimationDurtion(500); //设置适配器 rollPagerView.setAdapter(new TestNormalAdapter(imgs)); //自定义指示器 //rollPagerView.setHintView(new IconHintView(this,R.drawable.,R.drawable.)); //设置圆点指示器颜色 rollPagerView.setHintView(new ColorPointHintView(this, Color.BLUE,Color.WHITE)); //设置文字指示器 //rollPagerView.setHintView(new TextHintView(this)); //隐藏指示器 // rollPagerView.setHintView(null); rollPagerView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(int position) { kenBurnsView.setImageResource(imgs[position]); } }); } public class TestNormalAdapter extends StaticPagerAdapter{ private int[] imgs; public TestNormalAdapter(int[] imgs) { this.imgs = imgs; } @Override public View getView(ViewGroup container, int position) { ImageView view=new ImageView(container.getContext()); view.setImageResource(imgs[position]); view.setScaleType(ImageView.ScaleType.CENTER_CROP); view.setLayoutParams(new ViewGroup.LayoutParams( ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT )); return view; } @Override public int getCount() { return imgs.length; } } }
