我是Java编程的新手。大约一两个星期前开始。有图灵和Visual Basic的一些经验。请尽量保持解释尽可能简单。对不起，如果帖子有点乱，第一次在这里发帖。
这是我的src java文件
package com.example.pokethedot;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class PokeTheDot extends ActionBarActivity {
int counter;
Button add;
TextView display;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_poke_the_dot);
counter=0;
add=(Button) findViewById(R.id.bAdd);
display=(TextView) findViewById(R.id.tvDisplay);
add.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
counter++;
display.setText(counter);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.poke_the_dot, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
这是我的xml

答案 0 :(得分：1)
试试这个：
display.setText(String.valueOf(counter));
使用int作为setText的参数意味着您要使用字符串资源，在这种情况下，标识为#0x1的资源不存在。
答案 1 :(得分：0)
制作
int couter;
Button add;
最后，
final int counter;
final Button add;
并更改
display.setText(counter);
作为
display.setText(new String(counter));
这可能会解决您的问题。您必须在匿名类中使用最终变量。
