试试这个
imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
selectImage();
}
});
}
private void selectImage() {
final CharSequence[] items = {"Take Photo", "Choose from Library",
"Cancel"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
if (items[item].equals("Take Photo")) {
activeTakePhoto();
} else if (items[item].equals("Choose from Library")) {
activeGallery();
} else if (items[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
private void activeTakePhoto() { //open camera
String filename = "Pic_" + System.currentTimeMillis() + ".jpg";
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File photo = new File(Environment.getExternalStorageDirectory(), filename);
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
}
private void activeGallery() { // open gallery

startActivityForResult(intent, RESULT_LOAD_IMAGE);
}
