Question

请帮帮我。

我用 ImageView ListView 。我想在点击心形图像时将心脏图像的颜色更改为红色。然后我要显示所有点击的项目在favorites.it就像书签ListView项目

这是输出。

这是我的代码。

FragmentOne

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View rootView = inflater.inflate(R.layout.fragment_fragment_one, container, false);

        TabHost host = (TabHost) rootView.findViewById(R.id.tabHost);
        host.setup();

        //Tab 1
        TabHost.TabSpec spec = host.newTabSpec("SONG LIST");
        spec.setContent(R.id.tab1);
        spec.setIndicator("SONG LIST");
        host.addTab(spec);

            ArrayList<FragmentOne_slResults> slResults = GetSearchResults();
        final ListView sllv = (ListView) rootView.findViewById(R.id.slListView);
        sllv.setAdapter(new FragmentOne_Adapter(getActivity(), slResults));


        //Tab 2
        spec = host.newTabSpec("NEW SONGS");
        spec.setContent(R.id.tab2);
        spec.setIndicator("NEW SONGS");
        host.addTab(spec);

请帮帮我。

我正在开发一个歌剧应用程序，如来自Playstore的数字歌本。

Answer 1

您是否尝试在Viewholder中将其添加为ImageButton，然后在getView中为其添加SetOnclickListener？

holder.button = (ImageButton)convertView.findviewById( ... );
final ImageButton tmp = holder.button;
tmp.setOnClickListenet( ... ) ;

编辑：在您的XML而不是：

<ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/heart"
            android:layout_gravity="right|top" />

将其替换为：

<ImageButton
android:id  < add your ID here !!! >
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/heart"
            android:layout_gravity="right|top" />

Answer 2

这是我改变心脏颜色的代码。在你的布局xml文件中使用这个

<ToggleButton
     android:id="@+id/toggleButton"
     style="@style/toggleButton"
     android:layout_width="40dp"
     android:layout_height="40dp"
     android:layout_gravity="right"
     android:background="@drawable/favourite_toggle_bg"/>

在样式文件中添加此内容。

<style name="toggleButton"  parent="@android:Theme.Black">
    <item name="android:buttonStyleToggle">@style/Widget.Button.Toggle</item>
    <item name="android:textOn"></item>
    <item name="android:textOff"></item>
</style>

在drawable文件夹的favourite_toggle_bg.xml中创建新文件并添加此代码。

<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_checked="false"
              android:drawable="@mipmap/favourite_no" />
        <item android:state_checked="true"
              android:drawable="@mipmap/favourite_yes" />
    </selector>

将ToggleButton btnFavourite添加到你的持有人中并使用ToggleButton启动它

holder.btnFavourite = (ToggleButton) convertView.findViewById(R.id.toggleButton);

在java代码中，如果你想收藏Toggle按钮检查，那么在你的getView适配器方法中添加它

holder.btnFavourite.setChecked(true);
