一個按鈕的文本搜索
我在content_main.xml實施了一些按鈕通過搜索查看
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.ivmenusisla.MainActivity"
tools:showIn="@layout/app_bar_main">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:id="@+id/allRestaurants">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<Button
android:text="Blenders in the Grass"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableLeft="@drawable/blenders"
android:alpha="0.90"
android:id="@+id/blenders" />
<Button
android:text="Breakfast to Breakfast"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableLeft="@drawable/btob"
android:alpha="0.90"
android:id="@+id/btob" />
</LinearLayout>
</ScrollView>
</RelativeLayout>
我還增補搜索查看插件在我的main.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/action_search"
android:icon="@android:drawable/ic_menu_search"
android:title="search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always" />
</menu>
我怎麼能設置一個動作監聽器,以便當用戶點擊SearchView小部件並鍵入內容時,結果將基於每個按鈕的文本顯示出來?
我也有這個在我的MainActivity.java
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextChange(String newText) {
//Log.e("onQueryTextChange", "called");
return false;
}
@Override
public boolean onQueryTextSubmit(String query) {
// Do your task here
return false;
}
});
return true;
}
謝謝!
謝謝!我會照你說的去做! –
