我有一个应用程序,让您单击一个ImageButton,然后将您带到Android图库或相机.我正在寻找的是一个onActivityResult方法,它从单击/拍摄的图像中检索图像路径并将其存储在字符串中.
有人能帮我吗？这是打开图库/相机的onClick方法：
private void showImageDialog() {
final String [] items = new String [] {"From Camera","From SD Card"};

使用此代码,

.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"),SELECT_PICTURE);
}
});
public void onActivityResult(int requestCode,int resultCode,Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
Log.v("IMAGE PATH====>>>> ",selectedImagePath);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri,projection,null,null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
selectedImagePath是图像的路径.
