如何从SearchView移除焦点? [英] How to remove focus from SearchView?

问题描述

我想从onResume()中的SearchView中删除焦点和文本.

I want to remove focus and text from SearchView in onResume().

我尝试了searchView.clearFocus()，但是它不起作用.

I tried searchView.clearFocus() but it is not working.

这是我的xml代码:

<SearchView
    android:id="@+id/searchView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/toolbar"
    android:layout_alignTop="@+id/toolbar"
    android:layout_centerVertical="true"
    android:layout_marginBottom="4dp"
    android:layout_marginTop="4dp"
    android:iconifiedByDefault="false"
    android:paddingLeft="16dp"
    android:paddingRight="16dp" />

推荐答案

我想从onResume()

要实现此目的，您可以使用android:focusableInTouchMode属性将根布局设置为可聚焦，并请求将焦点集中在onResume()中的View.

To achieve this you could set your root layout focusable with the android:focusableInTouchMode attribute and request focus on that View in onResume().

例如:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/root_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:focusableInTouchMode="true">

    <SearchView
        android:id="@+id/search_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:iconifiedByDefault="false"/>

</LinearLayout>

然后在您的Activity中:

private View rootView;
private SearchView searchView;

// ...

@Override
protected void onCreate(Bundle savedInstanceState) {

    // ...

    rootView = findViewById(R.id.root_layout);
    searchView = (SearchView) findViewById(R.id.search_view);
}

@Override
protected void onResume() {
    super.onResume();

    searchView.setQuery("", false);
    rootView.requestFocus();
}
