I followed the instructions how to create a context menu but mine
shows up completely black and nothing in it. Anyone has already had
the same issue and can help me how he/she solved it?
Thanks
Here my class .java and menu .xml files
package com.MyProject;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.app.Activity;
import android.view.ContextMenu;
import android.view.View;
import android.view.ContextMenu.ContextMenuInfo;
public class ColorsActivity extends Activity {
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.context_menu, menu);
registerForContextMenu(v);
}
public boolean onContextItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.red:
if (item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
case R.id.blue:
if (item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
case R.id.green:
if (item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
case R.id.yellow:
if (item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
case R.id.black:
if (item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
case R.id.white:
if (item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
case R.id.orange:
if (item.isChecked()) item.setChecked(false);
else item.setChecked(true);
return true;
default:
return super.onContextItemSelected(item);
}
}
}
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android";>
<group android:checkableBehavior="single">
<item android:id="@+id/red"
android:title="@string/red"
android:checked="true" />
<item android:id="@+id/blue"
android:title="@string/blue" />
<item android:id="@+id/green"
android:title="@string/green" />
<item android:id="@+id/yellow"
android:title="@string/yellow" />

android:title="@string/black" />
<item android:id="@+id/white"
android:title="@string/white" />
<item android:id="@+id/orange"

</menu>
