SearchView 不调用 onOptionsItemSelected [英] SearchView Not call onOptionsItemSelected

问题描述

错误"好奇怪 其他时候我已经这样做了，但从未解决过这个问题......

"Error" Well Strange Other times I've done it and never tive this problem ...

如果我将appname:actionViewClass="android.support.v7.widget.SearchView"放在菜单上，我的搜索视图不会调用 onOptionsItemSelected.

My searchview not call onOptionsItemSelected if i put "appname:actionViewClass="android.support.v7.widget.SearchView" on menu.

清单

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />
 <activity
            android:name=".DashBoardActivity"
            android:label="">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

dash_board.xml(菜单)(如果我撤回他调用的 actionViewClass(onOptionsItemSelected)，但如果我放他不调用)

dash_board.xml (menu) (if I retreat actionViewClass he calls(onOptionsItemSelected ), but if i put he dont call)

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:appname="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.example.servic.DashBoardActivity" >


           <item android:id="@+id/action_search"
          android:icon="@drawable/ic_action_search"
          android:title="@string/action_search"
          appname:showAsAction="always"
          appname:actionViewClass="android.support.v7.widget.SearchView"/>

             <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:title="@string/action_settings"
        appname:showAsAction="always"/>



</menu>

仪表板活动

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.dash_board, menu);
        MenuItem searchItem = menu.findItem(R.id.action_search);
        mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.

        int id = item.getItemId();
        switch (id)
        {
        case R.id.action_search:
            mSearchView
            .setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
                @Override
                public void onFocusChange(View v, boolean hasFocus) {
                    if (hasFocus) {
                        ToastMensagem("Digite um endereço.");
                    } else {
                        BuscarEndereco(mSearchView.getQuery().toString());
                    }
                }



            });
            break;
        }


        return super.onOptionsItemSelected(item);
    }

错误是，不调用 onOptionsItemSelected，我需要操作 searchview

The error is, not call onOptionsItemSelected, i need manipulate searchview

推荐答案

请注意，提交搜索结果不应该使用 SearchView.setOnQueryTextFocusChangeListener

Just to note that for submitting search result you should not use SearchView.setOnQueryTextFocusChangeListener

应该使用 SearchView.setOnQueryTextListener 代替.

以下是搜索提交侦听器的示例:

Below is an example for Search Submit listener:

        case R.id.action_search:
            mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

                @Override
                public boolean onQueryTextSubmit(String query) {
                    Toast.makeText(getActivity(),
                            getString(R.string.abc_searchview_description_submit),
                            Toast.LENGTH_SHORT)
                            .show();
                    updateUI(query);
                    return true;
                }

                @Override
                public boolean onQueryTextChange(String query) {
                    // Clear search
                    if (query.equals("")) {
                        updateUI(null);
                    }
                    return true;
                }
            });
