ユーザーからの入力場所（「病院」など）をMapsActivityに渡して、付近の病院を地図上に表示できるようにしたいとします。私は以下のようにそれを渡そうとしましたが失敗しました。なぜなら、私は文字列 "検索"のログメッセージを表示するので、ログメッセージはlogcatに表示することができません。他のログメッセージを表示することはできますが、「検索」のログメッセージのみを表示することはできません。それで、どうすればいいですか？ 助けを得ることを望みます。ありがとう 以下は私のコードです。あなたのMapsActivityでMapsActivityにデータを渡すことができません
MainActivity
btnSearch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(MainActivity.this, MapsActivity.class);
intent.putExtra("search", searchWord);
startActivity(intent);
}
});
