Android 请帮助创建代码来计算按钮的点击率

我是一个新手开发人员。请帮助创建用于计算按钮点击次数的代码（在Android上）。我有三个ImageButton（IB1、IB2、IB3）和三个空文本视图（TV1、TV2、TV3）。但是，计数器不应被视为三个按钮中每个按钮的点击次数。计数器应被视为此会话中每个按钮的点击次数占所有三个按钮点击总数的百分比。这是我的代码的开头。提前感谢大家

public class ring_fight extends Activity implements View.OnClickListener {  



    ImageButton IB1, IB2, IB3;
    TextView TV1, TV2, TV3;

    // I declare counters
        int Count_for_IB1 = 0; //counter for ImageButton1 
        int Count_for_IB2 = 0; //counter for ImageButton2
        int Count_for_IB3 = 0;//counter for ImageButton3


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

        IB1 = (ImageButton) findViewById(R.id.IB_first);
        IB2 = (ImageButton) findViewById(R.id.IB_second);
        IB3 = (ImageButton) findViewById(R.id.IB_third);

        TV1 = (TextView)findViewById(R.id.TextView1);
        TV2 = (TextView)findViewById(R.id.TextView2);
        TV3 = (TextView)findViewById(R.id.TextView3);


        IB1.setOnClickListener(this);
        IB2.setOnClickListener(this);
        IB3.setOnClickListener(this);
    }

    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.IB1:
                TV1.setText("");
                break;
            case R.id.IB2:
                TV1.setText("");
                break;
            case R.id.IB3:
                TV1.setText("");
                break;
        }
    }
}

下面应该有帮助

public void onClick(View v) {
    switch (v.getId()) {
        case R.id.IB1:
            Count_for_IB1++;
            break;
        case R.id.IB2:
            Count_for_IB2++;
            break;
        case R.id.IB3:
            Count_for_IB3++;
            break;
    }
    TV1.setText((Count_for_IB1*100 / (Count_for_IB1 + Count_for_IB2 + Count_for_IB3)) + " %");
    TV2.setText((Count_for_IB2*100 / (Count_for_IB1 + Count_for_IB2 + Count_for_IB3)) + " %");
    TV3.setText((Count_for_IB3*100 / (Count_for_IB1 + Count_for_IB2 + Count_for_IB3)) + " %");
}

如何通过单个符号限制小数位数，例如33.6，但33.666666？谢谢，最后一行可能应该是这样的：TV3.setText（String.valueOf（（（count3/total）*100））；

float count1=0, count2=0, count3=0, total=0;
public void onClick(View v) {
    switch (v.getId()) {
          case R.id.IB1:
               count1++;
          break;
          case R.id.IB2:
               count2++;
          break;
          case R.id.IB3:
               count3++;
          break;
   }
   total=count1+count2+count3;
   TV1.setText(String.valueOf(((count1/total)/100)));
   TV2.setText(String.valueOf(((count2/total)/100)));
   TV3.setText(String.valueOf(((count3/total)/100)));
}
