我的应用程序因错误而崩溃：

android.content.res.Resources$NotFoundException: String resource ID #0x0

我只是不知道我做错了！

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());
        }
    });
}

}

最佳答案

您的问题很可能是由于originalPoints是整数并且您在points.setText(originalPoints);中使用它而引起的。 setText(int)构造函数需要一个资源ID，因此要显示实际值，必须先将其转换为字符串：

points.setText(String.valueOf(originalPoints));
