這篇文章主要為大家詳細(xì)介紹了Android scrollview實(shí)現(xiàn)底部繼續(xù)拖動(dòng)查看圖文詳情，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了Android實(shí)現(xiàn)底部拖動(dòng)查看圖文詳情的具體代碼，供大家參考，具體內(nèi)容如下

一、效果圖

二、實(shí)現(xiàn)步驟

1.xml布局的實(shí)現(xiàn)/p>

<ScrollView
 android:id="@+id/mymyscrollview"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:layout_above="@+id/rejcdosjflk"
 android:background="#ffffff"
 android:scrollbars="none">


 <LinearLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:layout_marginBottom="60dp"
  android:orientation="vertical">
  </LinearLayout>
 </ScrollView>

2.activity的實(shí)現(xiàn)

private ScrollView mScrollView;
mScrollView = (ScrollView) findViewById(R.id.mymyscrollview);
//調(diào)用方法
mScrollView.setOnTouchListener(new TouchListenerImpl());


private int scrollY;
private int height;
private int scrollViewMeasuredHeight;


private class TouchListenerImpl implements View.OnTouchListener {
 @Override
 public boolean onTouch(View view, MotionEvent motionEvent) {
  switch (motionEvent.getAction()) {
   case MotionEvent.ACTION_DOWN:


    break;
   case MotionEvent.ACTION_MOVE:
    scrollY = view.getScrollY();
    height = view.getHeight();
    scrollViewMeasuredHeight = mScrollView.getChildAt(0)
      .getMeasuredHeight();
    break;
   case MotionEvent.ACTION_UP:
    System.out.println("scrollY=" + scrollY);
    System.out.println("height=" + height);
    System.out.println("scrollViewMeasuredHeight="
      + scrollViewMeasuredHeight);
    if (scrollY == 0) {
     System.out.println("滑動(dòng)到了頂端 view.getScrollY()=" + scrollY);
    } else if ((scrollY + height) >= scrollViewMeasuredHeight) {
     Message msg = new Message();
     msg.what = 0;
     mHandlerht.sendMessage(msg);
    } else {
     System.out.println("滑動(dòng) height=" + height);
    }
    // 復(fù)位
    scrollY = 0;
    height = 0;
    scrollViewMeasuredHeight = 0;
    break;


   default:
    break;
  }
  return false;
 }


}

private Handler mHandlerht = new Handler() {
 public void handleMessage(Message msg) {
  switch (msg.what) {
   case 0:
    // 跳轉(zhuǎn)
    Intent intentcll = new Intent();
    intentcll.setClass(BDDetialActivityCll.this,
      CSProductDetailsCll.class);
    intentcll.putExtra("product", ncspbean);
    startActivity(intentcll);
    break;
   default:
    break;
  }
 }


};
