在 SearchView 中的文本后闪烁光标而不显示软键盘

Question

我正在尝试模仿 gmail 应用程序处理搜索的方式，如下所示：

如上所示，在 searchView 中搜索查询后有一个（蓝色）闪烁的光标。

我各自的代码如下所示：

SearchReslutActivity.class

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu, menu);

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    searchView.setQuery(getIntent().getStringExtra(SearchManager.QUERY), false);
    searchView.setIconified(false);
    searchView.clearFocus();

    return true;
}

menu/search_menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">

<item
    android:id="@+id/search"
    android:title="@string/search_title"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="always" /> </menu>

xml/searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:hint="@string/hint"
android:includeInGlobalSearch="true"
android:inputType="textCapWords"
android:label="@string/app_name"
android:searchSuggestAuthority="com.webaddress.myproject.data.Provider"
android:searchSuggestIntentAction="android.intent.action.VIEW"
android:searchSuggestIntentData="content://com.webaddress.myproject.data.Provider/table"
android:searchSuggestSelection=" ?"
android:searchSuggestThreshold="1" />

上面的代码实现了与 gmail 应用程序中显示的相同的外观 除了有一个闪烁的光标 。如何在不请求焦点在 searchView 上的情况下添加这样一个闪烁的光标（这又会使软键盘再次弹出）？

谢谢！

Answer 1

试试这个，

    searchView.setOnSearchClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
             searchView.setImeOptions(EditorInfo.IME_ACTION_SEARCH);
        }
    });

Answer 2

在onCreate()

中添加此代码

searchView.setOnFocusChangeListener(new View.OnFocusChangeListener() {

      @Override
      public void onFocusChange(View v, boolean hasFocus) {

          if (!searchView.hasFocus()) {
              //this if condition is true when searchview lost focus...
              int searchSrcText = searchView.getContext().getResources()
                  .getIdentifier("android:id/search_src_text", null, null);
              EditText editText = (EditText) searchView.findViewById(searchSrcText);
              editText.setCursorVisible(true);
              searchView.setActivated(true);
              searchView.setPressed(true);
          }
      }
});

执行此操作：

@Override
public boolean onCreateOptionsMenu(final Menu menu) {
    getMenuInflater().inflate(R.menu.search_menu, menu);
    return true;
}

@Override
public boolean onPrepareOptionsMenu(final Menu menu) {
    MenuItem menuItem = menu.findItem(R.id.search);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(menuItem);
    SearchView.SearchAutoComplete searchAutoComplete = 
        (SearchView.SearchAutoComplete) searchView.findViewById(R.id.search_src_text);
    searchAutoComplete.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(final View v, final boolean hasFocus) {
            v.requestFocus();
        }
    });
    return super.onPrepareOptionsMenu(menu);
}

search_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
            android:id="@+id/search"
            android:title="Search"
            app:actionViewClass="android.support.v7.widget.SearchView"
            app:showAsAction="ifRoom"/>

</menu>

使用支持库版本 25.3.0 进行测试。

多亏了@Azizbekian 的回答（对我来说它本身不起作用）我终于让它可以使用以下代码（在一个空项目中 - 支持 libs 25.3.0）：

java/MainActivity

package com.yourwebpage.yourapplication;

import android.app.SearchManager;
import android.os.Bundle;
import android.support.v4.view.MenuItemCompat;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.SearchView;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(final Menu menu) {
        getMenuInflater().inflate(R.menu.search_menu, menu);
        return true;
    }

    @Override
    public boolean onPrepareOptionsMenu(final Menu menu) {
        MenuItem menuItem = menu.findItem(R.id.search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(menuItem);
        searchView.setQuery(getIntent().getStringExtra(SearchManager.QUERY), false);
        searchView.setIconified(false);
        SearchView.SearchAutoComplete searchAutoComplete =
                (SearchView.SearchAutoComplete) searchView.findViewById(R.id.search_src_text);
        searchAutoComplete.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(final View v, final boolean hasFocus) {
                v.requestFocus();
            }
        });
        searchView.clearFocus();
        return super.onPrepareOptionsMenu(menu);
    }
}

res/layout/activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.yourwebpage.yourapplication.MainActivity">
</android.support.constraint.ConstraintLayout>

res/menu/search_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu

        android:title="Search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="always"/>
</menu>

manifests/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.yourwebpage.yourapplication">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity"
            android:windowSoftInputMode="stateAlwaysHidden">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

我发布了这个相当全面的解决方案，希望能够重现它。

此代码用于自定义工具栏

 SearchView.SearchAutoComplete searchTextView =  mSearchView.findViewById(R.id.search_src_text);
        try {
            Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
            mCursorDrawableRes.setAccessible(true);
            mCursorDrawableRes.set(searchTextView, 0);
            //This sets the cursor resource ID to 0 or @null which will make it visible on white background
        } catch (Exception e) {
            e.printStackTrace();
        }
