Java android.widget.AbsListView.OnScrollListener 代码实例

以下是展示如何使用android.widget.AbsListView.OnScrollListener的最佳示例。 我们使用了代码质量辨别算法从开源项目中提取出了最佳的优秀示例。

实例 1

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
    switch (scrollState) {
        case OnScrollListener.SCROLL_STATE_IDLE:
            imageLoader.resume();
            break;
        case OnScrollListener.SCROLL_STATE_TOUCH_SCROLL:
            if (pauseOnScroll) {
                imageLoader.pause();
            }
            break;
        case OnScrollListener.SCROLL_STATE_FLING:
            if (pauseOnFling) {
                imageLoader.pause();
            }
            break;
    }
    if (externalListener != null) {
        externalListener.onScrollStateChanged(view, scrollState);
    }
}
 

实例 2

public final void onScrollStateChanged(final AbsListView view, final int state) {
	/**
	 * Check that the scrolling has stopped, and that the last item is
	 * visible.
	 */
	if (state == OnScrollListener.SCROLL_STATE_IDLE && null != mOnLastItemVisibleListener && mLastItemVisible) {
		mOnLastItemVisibleListener.onLastItemVisible();
	}

	if (null != mOnScrollListener) {
		mOnScrollListener.onScrollStateChanged(view, state);
	}
}
 

实例 3

public void postSetSelection(final int position) {
  clearFocus();
  post(new Runnable() {

    @Override
    public void run() {
      setSelection(position);
    }
  });
  onScrollStateChanged(this, OnScrollListener.SCROLL_STATE_IDLE);
}
 

实例 4

public void onScrollStateChanged(AbsListView view, int scrollState) {
    switch (scrollState) {
    case OnScrollListener.SCROLL_STATE_IDLE:
        mBusy = false;
        
        int first = view.getFirstVisiblePosition();
        int count = view.getChildCount();
        for (int i=0; i<count; i++) {
            TextView t = (TextView)view.getChildAt(i);
            if (t.getTag() != null) {
                t.setText(mStrings[first + i]);
                t.setTag(null);
            }
        }
        
        mStatus.setText("Idle");
        break;
    case OnScrollListener.SCROLL_STATE_TOUCH_SCROLL:
        mBusy = true;
        mStatus.setText("Touch scroll");
        break;
    case OnScrollListener.SCROLL_STATE_FLING:
        mBusy = true;
        mStatus.setText("Fling");
        break;
    }
}
