我正在尝试编写一个包含2个网格视图的应用。网格视图在同一屏幕上并排显示。我用当前安装的应用程序填充左侧gridview并使用它们的图标,所以基本上我有一个ImageViews的gridview。该活动将Drawables的arraylist传递给ImageAdapter。 imageAdapter扩展了BaseAdapter并实现了OnTouchListener。我的getView()方法类似于Android开发者网站上的方法
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView imageView;
if (convertView == null)
{
// if it's not recycled, initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(6, 6, 6, 6);
}
else
{
imageView = (ImageView) convertView;
}
//imageView.setImageResource(mThumbIds[position]);
imageView.setImageDrawable(mList.get(position));
imageView.setContentDescription(mNames.get(position));
imageView.setDrawingCacheEnabled(true);
imageView.setOnTouchListener(this);
return imageView;
}
这是我的onTouch。我一直在关注其他示例,但我的场景不涉及使用AbsoluteLayout,它使用API级别8,因此我无法实现OnDragListener:(
public boolean onTouch(View v, MotionEvent event) {
LayoutParams par = (LayoutParams) v.getLayoutParams();
int x = (int) event.getX();
int y = (int) event.getY();
if (event.getAction() == MotionEvent.ACTION_DOWN)
{
Log.i("ACT DOWN", (String) v.getContentDescription());
status = START_DRAGGING;
v.setLayoutParams(par);
//image = new ImageView(mContext);
//mLayout.addView(image, par);
//Toast.makeText(AppMoverActivity.this, "" + v.getContentDescription(), Toast.LENGTH_SHORT).show();
}
if (event.getAction() == MotionEvent.ACTION_UP) {
status = STOP_DRAGGING;
v.setLayoutParams(par);
Log.i("ACT UP", "Stopped Dragging");
}
else if (event.getAction() == MotionEvent.ACTION_MOVE) {
if (status == START_DRAGGING) {
Log.i("ACT MOVE", "Moving");
//Implement ability to drag the view to other grid...
}
}
return true;
}
无论如何我可以做这项工作还是我必须改变我接近这个的方式?任何帮助表示赞赏!
