Question

我试图模仿gmail应用程序处理搜索的方式，如下所示：

如上图所示，searchView中的搜索查询后有一个（蓝色）闪烁光标。

我的代码如下：

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" />

上述代码与gmail应用程序中显示的内容完全相同，但光标闪烁除外。如何在不要求searchView焦点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

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);
          }
      }
});

感谢@ Azizbekian的回答（这对我来说不起作用）我终于使用了以下代码（在一个空项目中 - 支持libs 25.3.0）：

<强>的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);
    }
}

<强> RES /布局/ activity_main.xml中

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

<强>表现/ AndroidManifest.xml中

            </intent-filter>
        </activity>

</manifest>

我发布这个相当全面的解决方案，希望能让它再现。

Answer 4

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);
}

<强> 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。

Answer 5

此代码适用于自定义工具栏

 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();
        }

在SearchView中的文本后闪烁光标而不显示软键盘
