通过整数变量增加 TextView

Question

我有一个带有简单 onClick 方法的按钮。每次单击按钮时，我都希望我的 TextView 增加 1。例如，我的 TextView 显示 0 单击按钮时应显示 1，再次单击按钮时应显示 2...等等。我希望我的观点很明确 ;)

public class 游戏延长 Activity {

ViewGroup layout;
TextView score1;
String score;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.game);

    score1 = (TextView)findViewById(R.id.textView5);

    score = score1.getText().toString();

    layout = (ViewGroup) findViewById(R.id.frameLayout2);
    layout.setOnTouchListener(
            new RelativeLayout.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {

                    String presentValStr=score1.getText().toString();
                    int presentIntVal=Integer.parseInt(presentValStr);
                    presentIntVal++;
                    score1.setText(String.valueOf(presentIntVal));

                    return true;
                }
            }

                );
}

Answer 1

private int count=0; 

@Override public void onClick(View v) {
     count++;
     textView.setText(Integer.toString(count));
}
