I'm developing an android game, and I'm stuck with this problem.
This is the secondary activity, when I click the button that takes me to the second activity, it shows some errors, I'm trying to figure this out on my on by searching and experimenting by my self, but it didn't work
This is my activity :
package game.esolindo.com.gametest;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MoneyActivity extends ActionBarActivity {
private TextView txtMoney;
private Button btnWork;
private Button btnBuyClothes;
int workMoney = 15;
int buyClothesMoney = 20;
int currentMoney;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_money);
txtMoney = (TextView)findViewById(R.id.txtMoney);
btnWork = (Button)findViewById(R.id.btnWork);
btnWork.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
currentMoney = currentMoney + workMoney;
txtMoney.setText(String.valueOf(currentMoney));
}
});
btnBuyClothes = (Button)findViewById(R.id.btnBuyClothes);
btnBuyClothes.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
currentMoney = currentMoney - buyClothesMoney;
txtMoney.setText(String.valueOf(currentMoney));
}
});
txtMoney.setText(currentMoney);
}
}
This is my xml file :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context="game.esolindo.com.gametest.MoneyActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Money"
android:id="@+id/txtMoneyText"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="10dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:text="0"
android:textSize="50sp"
android:id="@+id/txtMoney"
android:layout_below="@+id/txtMoneyText"
android:layout_centerHorizontal="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Work"
android:id="@+id/btnWork"
android:layout_marginTop="20dp"
android:layout_below="@+id/txtMoney"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Buy Clothes"
android:id="@+id/btnBuyClothes"
android:layout_below="@+id/btnWork"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
And this is the error message I received :
