我想从画廊获得这在网格视图照片的路径。这个画廊由附加复选框每个缩略图。这里是整个code：
I am trying to get path of photo from gallery which in grid view. this gallery consists of each thumbnail with attached checkbox. Here is the whole code:
public class GridGallery extends Activity
{
ArrayList<String>list;
AlertDialog.Builder alert;
private Button send;
GridView gridView;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.grid_gallery);
DataModel dbModel = new DataModel(this);
list = dbModel.selectAll();
alert = new AlertDialog.Builder(GridGallery.this);
send = (Button)findViewById(R.id.send_message);
gridView = (GridView) findViewById(R.id.sdcard);
gridView.setAdapter(new ImageAdapter(this));
gridView.setClickable(true);
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int pos,
long id)
{
// TODO Auto-generated method stub
final int position = pos;
final String path = list.get(position).toString();
final String option[] = new String[]{"Send to","Watch"};
alert.setTitle("Pick options");
alert.setItems(option, new OnClickListener() {
public void onClick(DialogInterface dialog, int which)
{
// TODO Auto-generated method stub
if(option[which].equals("Watch"))
{
if(path.contains(".jpg"))
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(list.get(position))), "image/jpeg");
startActivity(intent);
}
else if(path.contains(".mp4"))
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(list.get(position))), "video/*");
startActivity(intent);
}
else
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(list.get(position))), "audio/*");
startActivity(intent);
}
}//
else
{
Intent sendMail = new Intent(GridGallery.this, SendMessage.class);
sendMail.putExtra("path", path);
startActivity(sendMail);
}
}
}).show();
}
});
send.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
// TODO Auto-generated method stub
String path = null;
Intent sendToMail = new Intent(GridGallery.this, SendMessage.class);
sendToMail.putExtra("path", path);
startActivity(sendToMail);
}
});
}
/**
* Adapter for our image files.
*/
private class ImageAdapter extends BaseAdapter
{
private final Context context;
Bitmap bitmap;
public ImageAdapter(Context localContext) {
context = localContext;
}
public int getCount()
{
return list.size();
}
public Object getItem(int position)
{
return position;
}
public long getItemId(int position)
{
return position;
}
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView picturesView;
View myView = convertView;
if (convertView == null)
{
LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);//getLayoutInflater();
myView = layoutInflater.inflate(R.layout.image_selection, null);
picturesView = new ImageView(context);
picturesView = (ImageView)myView.findViewById(R.id.item_grid);
picturesView.setClickable(true);
if(list.get(position).contains(".jpg"))
{
bitmap = BitmapFactory.decodeFile(list.get(position));
}
else if(list.get(position).contains(".mp4"))
{
bitmap = ThumbnailUtils.createVideoThumbnail(list.get(position), 0);
}
else
{
}
picturesView.setImageBitmap(bitmap);
picturesView.setScaleType(ImageView.ScaleType.FIT_CENTER);
picturesView.setPadding(8, 8, 8, 8);
return myView;
}
else
{
myView = convertView;
return myView;
}
}
}
}
我的问题是我能不能够点击图片或视频的缩略图。还我怎么能够得到图像时我检查的复选框。
MY problem is I can not be able to click the image or video thumbnail. also how do I able to get the image when I checked the check box.
下面是XML code为Image_selection： -
here is XML code for Image_selection:-
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical" android:gravity="center_horizontal">
<ImageView android:id="@+id/item_grid" android:layout_width="100dip" android:layout_height="100dip"/>
<CheckBox android:id="@+id/check" android:layout_width="wrap_content" android:layout_height="wrap_content" />
和grid_gallery.xml： -
and grid_gallery.xml:-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical">
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/sdcard"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:numColumns="auto_fit"
android:columnWidth="90dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>
</RelativeLayout>
请帮助我。在此先感谢
推荐答案
看来你存储在ArrayList的列表中的图片路径。如果是这样，然后设置为GridView的 onItemClickListeber 。在 onItemClick 方法，你这是点击GridView控件的位置。尝试'list.get（位置）在 onItemClick`获得路径
it seems you store the image path in the ArrayList list. If so, then set an onItemClickListeber for the GridView. in the onItemClick method you get the position of the gridview which was clicked. try 'list.get(position)in theonItemClick` to get the path
