マイアプリ：
android.content.res.Resources$NotFoundException: String resource ID #0x0
私はちょうど私が間違っていたかわかりません！
public class WithdrawPoints extends AppCompatActivity {
private Firebase myRef;
private SharedPreferences.Editor accountEditor;
private static final String Firebase_URL = "https://myfirstproject-545a7.firebaseio.com/";
private int withdrawPoints;
private int originalPoints;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gain_rewards);
ImageView view = (ImageView) findViewById(R.id.imageView5);
view.setAlpha(127);
myRef = new Firebase(Firebase_URL);
TextView points = (TextView) findViewById(R.id.textView9);
originalPoints = User.getInstance().getPoints();
points.setText(originalPoints);
EditText editText = (EditText) findViewById(R.id.editText4);
withdrawPoints = Integer.valueOf(editText.getText().toString());
final Button withdrawButton = (Button) findViewById(R.id.button7);
withdrawButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
User.getInstance().setPoints(originalPoints-withdrawPoints);
myRef.child("users").child(User.getInstance().getPhone()).setValue(User.getInstance());
}
});
}
}
