android图片加文字轮播效果，RollViewPager使用，简单修改源代码
简单看下效果图：
主要支持的一些功能：
支持无限循环。 触摸时会暂停播放，直到结束触摸一个延迟周期以后继续播放。 看起来就像这样。图片变化 文字也跟着变化。
主要操作过程：
1、在gradle中导入包：
compile
'com.jude:rollviewpager:1.2.9'
然后就是一些简单的操作了：
布局如下：
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <FrameLayout android:layout_width="match_parent" android:layout_height="180dp" android:layout_alignParentTop="true" android:layout_alignParentStart="true"> <com.jude.rollviewpager.RollPagerView android:id="@+id/roll_view_pager" android:layout_width="match_parent" android:layout_height="180dp" app:rollviewpager_play_delay="3000"/> <TextView android:id="@+id/text" android:background="#88000000" android:layout_width="match_parent" android:layout_height="30dp" android:textColor="@android:color/holo_orange_dark" /> </FrameLayout> </RelativeLayout>
然后上代码：
import android.graphics.Color; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.util.Log; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import android.widget.TextView; import android.widget.Toast; import com.jude.rollviewpager.RollPagerView; import com.jude.rollviewpager.adapter.StaticPagerAdapter; public class MainActivity extends AppCompatActivity { private RollPagerView mRollViewPager; TextView t1 ; static MainActivity instance; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); instance = this; mRollViewPager = (RollPagerView) findViewById(R.id.roll_view_pager); t1 = (TextView) findViewById(R.id.text); //设置播放时间间隔 mRollViewPager.setPlayDelay(2500); //设置透明度 mRollViewPager.setAnimationDurtion(500); //设置适配器 mRollViewPager.setAdapter(new TestNormalAdapter()); //设置指示器（顺序依次） //自定义指示器图片 //设置圆点指示器颜色 //设置文字指示器 //隐藏指示器 //mRollViewPager.setHintView(new IconHintView(this, R.drawable.point_focus, R.drawable.point_normal)); mRollViewPager.setHintView(new ColorPointHintView(this, Color.YELLOW,Color.WHITE)); //mRollViewPager.setHintView(new TextHintView(this)); //mRollViewPager.setHintView(null); } private class TestNormalAdapter extends StaticPagerAdapter { private int[] imgs = { R.drawable.img1, R.drawable.img2, R.drawable.img3, R.drawable.img4, }; @Override public View getView(ViewGroup container, int position) { final int picNo = position+1; 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)); Log.i("info","cha kan position:"+position); view.setOnClickListener(new View.OnClickListener() // 点击事件 { @Override public void onClick(View v) { Toast.makeText(MainActivity.this, "点击了第" + picNo + "张图片", Toast.LENGTH_SHORT).show(); } }); view.getImageAlpha(); return view; } @Override public int getCount() { return imgs.length; } } @Override public boolean onCreateOptionsMenu(Menu menu) { return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { return super.onOptionsItemSelected(item); } public void buju(int a){ switch (a){ case 1: t1.setText("我是第1张图"); break; case 2: t1.setText("我是第2张图"); break; case 3: t1.setText("我是第3张图"); break; case 4: t1.setText("我是第4张图"); break; } } }这里需要重写 RollViewPager里面两个类的代码才能实现 文字 图片一起滚动：
import android.content.Context; import android.graphics.drawable.Drawable; import android.util.AttributeSet; import android.view.Gravity; import android.widget.ImageView; import android.widget.LinearLayout; import com.jude.rollviewpager.HintView; public abstract class ShapeHintView extends LinearLayout implements HintView { private ImageView[] mDots; private int length = 0; private int lastPosition = 0; private Drawable dot_normal; private Drawable dot_focus; public ShapeHintView(Context context){ super(context); } public ShapeHintView(Context context, AttributeSet attrs) { super(context, attrs); } public abstract Drawable makeFocusDrawable(); public abstract Drawable makeNormalDrawable(); @Override public void initView(int length, int gravity) { removeAllViews(); setOrientation(HORIZONTAL); switch (gravity) { case 0: setGravity(Gravity.LEFT| Gravity.CENTER_VERTICAL); break; case 1: setGravity(Gravity.CENTER); break; case 2: setGravity(Gravity.RIGHT| Gravity.CENTER_VERTICAL); break; } this.length = length; mDots = new ImageView[length]; dot_focus = makeFocusDrawable(); dot_normal = makeNormalDrawable(); for (int i = 0; i < length; i++) { mDots[i]=new ImageView(getContext()); LayoutParams dotlp = new LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); dotlp.setMargins(10, 0, 10, 0); mDots[i].setLayoutParams(dotlp); mDots[i].setBackgroundDrawable(dot_normal); addView(mDots[i]); } setCurrent(0); } @Override public void setCurrent(int current) { if (current < 0 || current > length - 1) { return; } mDots[lastPosition].setBackgroundDrawable(dot_normal); mDots[current].setBackgroundDrawable(dot_focus); lastPosition = current; MainActivity.instance.buju(current+1); } }第二个 这样就实现了文字 图片一起滚动！
