Android – change the text color of listview items
•
Android
How to change the text color of the item added to the listview. I need to change the color programmatically in the code according to some conditions, and change different lines to different text colors (for example, line 0 = red, line 1 = white, line 3 = blue, etc.). Setting the text color in the XML layout will not meet my requirements. This is my code:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
setlistadapter(new ArrayAdapter<String>(ListViewEx.this,
R.layout.list_item_1, Global.availableDecks));
//something like this
//listview.getPosition(0).setTextColor(red);
//listview.getPosition(1).setTextColor(white);
//listview.getPosition(2).setTextColor(blue);
And my XML:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/label"
android:layout_width="match_parent"
android:layout_height="35dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="30px"
android:layout_marginLeft="5px"
android:singleLine="true"
/>
resolvent:
Implement your own arrayadapter and override the getview () method:
public class Adapter1 extends ArrayAdapter<String> {
public Adapter1(Context context, int resID, ArrayList<String> items) {
super(context, resID, items);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);
if (position == 1) {
((TextView) v).setTextColor(Color.GREEN);
}
return v;
}
}
Don't forget to provide an alternative else clause to set the color to the default color, so that you have no problem when dealing with circular rows. Then in your activity:
setlistadapter(new Adapter1(ListViewEx.this,
R.layout.list_item_1, Global.availableDecks));
