无法设置文字

Question

我需要设置Text with variable,我收到错误:

无法在基本类型int上调用setText(String)

这是我的代码:

    public class CalcActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
    private int mCount = 0;
    @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

}
    public void onClick(View v) {
          // TODO Auto-generated method stub
    switch(v.getId())
          {
          case R.id.CountBtn:
               mCount++;
           R.id.TextViewCount.setText("You clicked " + mCount + "times");
           break;
          case R.id.ResetBtn:
           // Do something
           break;
          }
         }  
}

你不能调用setTextid(R.id.TextViewCount),因为它是一个int,但在视图上.替换这个:

R.id.TextViewCount.setText("You clicked " + mCount + "times");

有了这个:

TextView v = (TextView)findViewById(R.id.TextViewCount);
v.setText("You clicked " + mCount + "times");
