Android 搜索活动从未被调用

我的清单文件：

            </intent-filter>
        </service>

        <activity android:name=".MainActivity" android:theme="@style/AppTheme.NoActionBar">

        </activity>

        <activity android:name=".AfterRegActivity" android:theme="@style/AppTheme.NoActionBar">

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


    </application>

</manifest>

在我的主要活动（带有工具栏和搜索小部件的活动）中：

---

我不知道为什么“doMySearch”方法永远不会被调用

将代码放在onNewIntent中，而不是onCreate中

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
 if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
        String query = intent.getStringExtra(SearchManager.QUERY);
        doMySearch(query);
    }
}

而不是

 @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
   // setContentView(R.layout.search);
    doMySearch("hi");
    // 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);
    }
}

我以前也做过类似的搜索应用。这是我的工作代码。
AndroidManifest.xml

        <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
            <meta-data
                android:name="android.app.default_searchable"
                android:value=".SearchActivity" />
        </intent-filter>
    </activity>
    <activity
        android:name=".SearchActivity"
        >
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
    </activity>

最后是搜索活动

public class SearchActivity extends AppCompatActivity {
    TextView tvSearch;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search);
        tvSearch = (TextView) findViewById(R.id.tvSearchQuery);
        handleIntent(getIntent());
    }

    @Override
    protected void onNewIntent(Intent intent) {
        setIntent(intent);
        handleIntent(intent);
    }

    private void handleIntent(Intent intent) {
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            doMySearch(query);
        }
    }

    private void doMySearch(String query) {
        tvSearch.setText(query);
    }
}

确保

xml/searchable

没有硬编码字符串。在MainActivity下添加就可以了。很高兴它起到了作用。

        <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
            <meta-data
                android:name="android.app.default_searchable"
                android:value=".SearchActivity" />
        </intent-filter>
    </activity>
    <activity
        android:name=".SearchActivity"
        >
        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
    </activity>

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.search, menu);
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.search).getActionView();
    ComponentName component = new ComponentName(this, SearchActivity.class);
    searchView.setSearchableInfo(searchManager.getSearchableInfo(component));
    searchView.setSubmitButtonEnabled(true);
    return true;
}  

public class SearchActivity extends AppCompatActivity {
    TextView tvSearch;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search);
        tvSearch = (TextView) findViewById(R.id.tvSearchQuery);
        handleIntent(getIntent());
    }

    @Override
    protected void onNewIntent(Intent intent) {
        setIntent(intent);
        handleIntent(intent);
    }

    private void handleIntent(Intent intent) {
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
            doMySearch(query);
        }
    }

    private void doMySearch(String query) {
        tvSearch.setText(query);
    }
}
