Android EditText 弹出软盘需要搜索按钮并监听

在布局中加入两句

android:imeOptions="actionSearch"
android:singleLine="true"

etSearch.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH) {//软盘搜索键
      ------
            return true;
        }
        return false;
    }
});
