My activity contains a ListView that is populated from an SQLite Database. However I find that the items on the ListView are not clickable. They are not clickable at all in the emulator or on the device. I know there are a lot of similar questions and I tried every possible one of them but to no avail. Please help me make the items clickable.
My Activity Code :
package com.tintin.scheduler_3;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.widget.SimpleCursorAdapter;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ListView;
public class List_Course extends ListActivity {
DatabaseHelper db;
SimpleCursorAdapter dataAdapter;
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.course_list);
Button add = (Button) findViewById(R.id.add);
add.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
startActivity(new Intent(List_Course.this, Add_Course.class));
}
});
Log.v("Button", "On Click Done");
db = new DatabaseHelper(List_Course.this);
Log.v("Button", "On Click Done2");
displayList();
Log.v("Button", "On Click Done3");
db.close();
}
public void onResume(){
Cursor newCursor = db.getAllCourses();
dataAdapter.changeCursor(newCursor);
super.onResume();
db.close();
}
public void displayList(){
Cursor cursor = db.getAllCourses();
String from [] = new String[] {db.colName,db.colDisplay};
int to[] = new int[] {R.id.textView1, R.id.textView2};
dataAdapter = new SimpleCursorAdapter(this, R.layout.listitem, cursor, from, to, 0){
public View getView(int position, View convertView, ViewGroup parent){
final View row = super.getView(position, convertView, parent);
if(position % 2 == 0)
row.setBackgroundColor(Color.parseColor("#D8D8D8"));
else
row.setBackgroundColor(Color.parseColor("#D0D0D0"));
return row;
}
};
ListView lv = getListView();
lv.setAdapter(dataAdapter);
registerForContextMenu(lv);
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Log.v("Click","Anything "+arg2+" "+arg3);
}
});
cursor.close();
db.close();
}
}
The Layout of this Activity :- (NOTE: I found that without the TextView the list populated from bottom up even though android:stackfromBottom was not set. So I put in the TextView and put the ListView below that)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:background="#D0D0D0" >
<Button
android:id="@+id/add"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Add a Course" />
<TextView
android:id="@+id/tv"
android:layout_width="match_parent"
android:layout_height="1dp"
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false" >
</TextView>
<ListView
android:id="@+id/android:list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/tv"
android:layout_above="@+id/add"
android:layout_alignParentLeft="true"
android:divider="#FFFFFF"
android:clickable="true"
android:dividerHeight="2dp" >
</ListView>
</RelativeLayout>
And the listitem.xml that defines how rows are to be shown in the listview :-
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/textView1"
android:focusableInTouchMode="false"
android:clickable="false"
android:focusable="false"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>
EDIT:: - I noticed that the items on my ListView are actually clickable. The problem however is that on clicking the list items the orange selection color is not shown. So unless the log is checked, it is not apparent which row was clicked on.However if I remove the part where I am overriding the getView method of the SimpleCursorAdapter while defining dataAdapter, on clicking the items there is an orange selection color that appears in the background of the clicked row.
In other words I am not getting any color for the focused row in list view.
Please run it in one of AVDs to understand what I am trying to say here. I would appreciate if anyone can help me get that color while also overriding the getView method.
