我有一个带有imageview和textview的自定义列表视图。我想当用户选择一个项目时,textview颜色应该改变,所有其他textview应保持默认。
这是我的xmls
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/listViewBell"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
android:choiceMode="singleChoice"
android:divider="#b5b5b5"
android:dividerHeight="1dp"
android:listSelector="@drawable/list_selector" />
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dip" >
<TextView
android:id="@+id/txt_bell_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="@string/rihanna_love_the_way_lie"
android:textColor="@color/black"
android:textSize="15sp"
android:textStyle="bold"
android:typeface="sans" />
<ImageView
android:id="@+id/list_bell_image"
android:layout_width="50dip"
android:layout_height="50dip"
android:src="@drawable/bronze_bell" />
</RelativeLayout>

在drawable
中创建以下button_text.xml<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#ffff0000"/> <!-- pressed -->
<item android:state_focused="true"
android:color="#ff0000ff"/> <!-- focused -->
<item android:color="#ff000000"/> <!-- default -->
</selector>
将文本视图的textColor更改为:
<TextView
android:id="@+id/txt_bell_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="@string/rihanna_love_the_way_lie"
android:textColor="@color/button_text" //point to that xml
android:textSize="15sp"
android:textStyle="bold"
android:typeface="sans" />

就像其他人所说的那样,只需更改onItemClick方法中的颜色即可。此外:
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectItem(position);
setItemNormal();
View rowView = view;
setItemSelected(rowView);
}
public void setItemSelected(View view){
View rowView = view;
TextView tv = (TextView)rowView.findViewById(android.R.id.text1);
tv.setTextColor(Color.BLUE);
}
public void setItemNormal()
{
for (int i=0; i< mDrawerList.getChildCount(); i++)
{
View v = mDrawerList.getChildAt(i);
//TextView txtview = ((TextView) v.findViewById(R.id.menurow_title));
TextView txtview = ((TextView)v.findViewById(android.R.id.text1));
txtview.setTextColor(Color.BLACK);
}
}
通过这样做,我们将所有项目设置为正常,然后再按每个项目更改它。

为此,您必须为该特定ImageView设置OnClickListener,然后在Adapter Class中单击ImageView更改TextView的颜色。
或者,
mList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
TextView tv= view.findViewById(resID);
tv.setTextColor(color)
}
});

为listView
实施setOnItemClickListener
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position,
long arg3) {
RelativeLayout relativeLayout = (RelativeLayout) view.getParent();
TextView textView = (TextView) relativeLayout.getChildAt(0);
ImageView imaegView = (ImageView) relativeLayout.getChildAt(1);
textView.setTextColor(Color.RED);
// Perform whatever action for your textView and imageView
}
});

经过多次尝试在导航视图中设置颜色,我发现了在列表视图中设置文本颜色的最简单方法,也许对某人有帮助
res / color / listview_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- This is used when the navigation item is selected -->
<item android:state_enabled="true"
android:state_activated="true" android:color="@color/colorAccent" />
<!-- This is the default text color -->
<item
android:color="@android:color/black" />
</selector>
并在 TextView 中设置为 android:textColor :
<TextView
android:id="@+id/tvItem"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="@dimen/activity_vertical_extra_margin"
android:textColor="@color/listview_selector"
android:textSize="@dimen/text_size_normal"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
tools:text="Row item text" />
问题处于正确的状态,请在导航视图中使用 android:state_activated
