[英]StateList for Compound ListView Row
When I click a row in my ListView the row is using the statelist but the individual elements are not. 当我单击ListView中的一行时,该行正在使用状态列表,但各个元素未使用。
So, I want to click a row in the ListView and have the states of the individual items updated. 因此,我想单击ListView中的一行,并更新各个项目的状态。 Obviously missing something. 显然缺少一些东西。
I have the following row in a ListView: 我在ListView中有以下行:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_row"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="@drawable/statelist_row" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.1" >
<ImageView
android:id="@+id/product_image"
style="@style/list_image"
android:contentDescription="@string/product_image" />
<ProgressBar
android:id="@+id/product_image_progress"
style="@style/list_image"
android:visibility="gone" />
</FrameLayout>
<TextView
android:id="@+id/product_name"
style="@style/list_text"
android:layout_weight="0.9"
android:gravity="center_vertical" />
<ImageView
style="@style/list_caret"
android:layout_weight="0.1"
android:contentDescription="@string/caret" />
</LinearLayout>
In the adapter I make the row clickable: 在适配器中,使该行可单击:
holder.productListRow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context, "CLICKED: '" + holder.productName.getText().toString() + "'", Toast.LENGTH_LONG).show();
}
});
I have a statelist that is applied in the styles: 我有一个应用于样式的状态列表:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@color/selected_item" android:state_pressed="true" android:textColor="@color/white" android:color="@color/white"/>
<item android:drawable="@color/std_background" android:color="@color/black"/>
</selector>
From colors: 从颜色:
<color name="list_text_color">@drawable/statelist_produce_row</color>
Finally, from styles: 最后,从样式:
<style name="list_text" parent="fill_parent">
<item name="android:textSize">@dimen/list_text_size</item>
<item name="android:textColor">@color/list_text_color</item>
<item name="android:layout_gravity">left|center_vertical</item>
<item name="android:padding">@dimen/list_text_padding</item>
<item name="android:textStyle">bold</item>
</style>
Shouldn't you make the listview items clickable by setting an onItemClickListener for the listview instead of making each row clickable? 您是否不应该通过为列表视图设置onItemClickListener而不是使每一行都可以单击来使列表视图项目可点击?
Try this 尝试这个
mListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
...
}
});
or if you're extending the ListActivity, you can directly implement onListItemClick(): 或者,如果要扩展ListActivity,则可以直接实现onListItemClick():
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
...
}
