特殊ステータス時の可視性を変更したい
だから私はそれが好きです
else {
ImageView image_A_wrong = (ImageView)findViewById(R.id.imageView1);
image_A_wrong.setVisibility(View.GONE);
}
しかし、Eclipseでエラーが表示されます。
なぜなのかご存知ですか ？
私のイメージビュー
<ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/quo100px" android:visibility="gone" />
Tksはすべて進めます
