有什么办法可以从gridview
.
我想item
从我的gridview
.
我没有找到任何东西。我的代码是
public class ImageAdapter extends BaseAdapter{
Context context;
public ImageAdapter(Context context)
{
this.context = context;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return mThumbIds.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return 0;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final ImageView imageView;
if (convertView == null) { // if it's not recycled, initialize some attributes
imageView = new ImageView(context);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(0, 5, 0, 0);
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
public Integer[] mThumbIds = {
R.drawable.sample_1,R.drawable.sample_2,R.drawable.sample_3,
R.drawable.sample_3,R.drawable.sample_1,R.drawable.sample_2,
R.drawable.sample_2,R.drawable.sample_3,R.drawable.sample_1
};
}
/////////////////
public class ImageActivity extends Activity {
ImageAdapter iAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image);
iAdapter = new ImageAdapter(this);
final GridView gView = (GridView)findViewById(R.id.grid_view);
gView.setAdapter(iAdapter);
gView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
//gView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
// gView.setItemChecked(position, true);
Toast.makeText(ImageActivity.this, "" + position, Toast.LENGTH_SHORT).show();
}
});
iAdapter.notifyDataSetChanged();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_image, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId() == R.id.menu_delete)
{
Toast.makeText(this, "Delete",Toast.LENGTH_SHORT ).show();
}
return super.onOptionsItemSelected(item);
}
}
任何人都可以有想法。感谢
