在我的onClick方法中,我调用了两个新的意图,一个用于使用相机拍照,另一个用于从图库中选择图像。但是,每当我在开始活动之前允许两个意图时,弹出允许对话总是互相停留。
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);
Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto , 1);
我将首先看到允许从图库中选择图像的选项,然后在向下滑动之后,我会看到允许相机的选项。如何在一个弹出窗口中显示它?

您可以执行以下操作....
private void showPickImageDialog() {
AlertDialog.Builder builderSingle = new AlertDialog.Builder(MainActivity.this);
builderSingle.setTitle("Select One Option");
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
MainActivity.this,
android.R.layout.select_dialog_singlechoice);
arrayAdapter.add("Gallery");
arrayAdapter.add("Camera");
builderSingle.setNegativeButton(
"cancel",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builderSingle.setAdapter(
arrayAdapter,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case 0:
Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto, 1);
break;
case 1:
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);
break;
}
}
});
builderSingle.show();
}
希望这对你有用!!
