在Oncreate方法中显示图库中的图像，而不打开图库意图

public class MainActivity extends AppCompatActivity {
    private static final int PICK_IMAGE_REQUEST = 1;
    private ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        imageView = findViewById(R.id.imageView);

        Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(intent, PICK_IMAGE_REQUEST);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null) {
            Uri imageUri = data.getData();
            Bitmap bitmap = null;
            try {
                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri);
            } catch (IOException e) {
                e.printStackTrace();
            }
            imageView.setImageBitmap(bitmap);
        }
    }
}
