Question

使用searchview显示内置搜索的代码。请问有人告诉我它有什么问题吗？ SearchableActivity在scr中创建 - ＆gt;演示文稿，它使用名为search.xml的xml布局。我是android新手，无法找出我的代码有什么问题。当启动搜索视图键入一个单词并按下键盘上的“Go”时，调试器会打开一个ActivityThread.perfor ....并告诉我找不到源。

这是我的洞manifest.xml：

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

    <meta-data
        android:name="android.app.default_searchable"
        android:value=".SearchableActivity" />
    <activity android:name=".SearchableActivity" >

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
        </intent-filter>

        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
    </activity>
</application>

    import myTV.Android.R;
    import android.app.Activity;
    import android.app.SearchManager;
    import android.content.Context;
    import android.content.Intent;
    import android.os.Bundle;
    import android.widget.Toast;

    public class SearchableActivity extends Activity{

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.search);

    // Get the intent, verify the action and get the query
    Intent intent = getIntent();
    if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
      String query = intent.getStringExtra(SearchManager.QUERY);
      doMySearch(query);
    }
}
public void doMySearch(String query){
    //new Request().Search(query);
    //new SearchEpisodes().Search(query);
    Context context = getApplicationContext();
    CharSequence text = query;
    int duration = Toast.LENGTH_LONG;

    Toast toast = Toast.makeText(context, text, duration);
    toast.show();
}


    }

这是我的searchable.xml：

    <searchable xmlns:android="http://schemas.android.com/apk/res/android"
        android:label="@string/app_name"
        android:hint="@string/SearchHint" >
</searchable>

Answer 1

我认为，您的活动在应用程序之外是不可见的。

尝试android:exported="true"。

Answer 2

尝试在<intent-filter>中添加以下内容。

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

无法启动可搜索的活动
