我想从我的
Android设备获取所有图像/照片/壁纸与图像保存路径.
我已经实现了从sdcard收集图像的代码,如下所示：
String[] mProjection = {
MediaStore.Images.Media._ID,MediaStore.Images.Media.DATA
};
mCursor = cr.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,mProjection,null,MediaStore.Images.Media.DEFAULT_SORT_ORDER);
从上面的代码我只能从sdcard中检索图像.但如果图像在设备手机内存中可用,那么我该如何检索图像/照片/壁纸？
如果我使用INTERNAL_CONTENT_URI它不会返回wallapers info其他图像信息
请任何身体帮助我….
解决方法
试试这个答案,这将有效：
public static final int GALLERY_CODE = 322;
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(
intent,"Select Picture"),GALLERY_CODE);
@Override
protected void onActivityResult(int requestCode,int resultCode,Intent data) {
//Assinging on corresponding import
super.onActivityResult(requestCode,resultCode,data);
if (requestCode == GALLERY_CODE && resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
try {
//add logic for coping file
} catch (Exception e) {
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri,projection,null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
