public class RegisterActivity extends AppCompatActivity { private ImageView iv; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_register); iv = (ImageView) findViewById(R.id.iv_hand); iv.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK,null); intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"image/*"); startActivityForResult(intent,100); } }); }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK && requestCode == 100) {
            if (data != null) {
                iv.setImageURI(data.getData());
            }
        }
    }
}
