我是编程新手，我很难弄清楚这一点。我正在尝试在平板电脑的每一侧创建两个可见的单独计数器。一个是数位板的左侧，另一个是数位板的右侧。当我单击左侧按钮时，它会更新左侧的计数（例如，1+1+1 等），但是当我单击右侧计数器时，它会添加一个附加值以在左侧计数器上求和。（例如，单击右侧（添加 1，然后当我单击左侧计数器时，它的作用类似于添加 2，而不是 1。）

这是我的代码到目前为止的样子

import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import android.widget.Button;
import android.widget.EditText;
import android.view.View;
import android.view.View.OnClickListener;



public class swim2 extends Activity {

// References to UI views
EditText txtCount;
EditText txtCount2;
Button PUp;
Button NUp;


static int Count = 0;    // Initial count
static int Count2 = 0;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
      super.onCreate(savedInstanceState);
        setContentView(R.layout.main3);
    // TODO Auto-generated method stub




        Button previous = (Button) findViewById(R.id.button4);
        previous.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                 Intent myIntent = new Intent(view.getContext(), swim1.class);
                    startActivityForResult(myIntent, 0);
            }

        }); 
     // Retrieve references to UI views by their id in XML layout
        NUp = (Button)findViewById(R.id.incremintationbutton2);    
        txtCount2 = (EditText)findViewById(R.id.ni); 
        txtCount2.setText(String.valueOf(Count2)); //Set initial value


        NUp = (Button)findViewById(R.id.incremintationbutton2);
        // Process the button on-click event
        NUp.setOnClickListener(new OnClickListener() {

           public void onClick(View Button) {
               Count++;
               txtCount2.setText(String.valueOf(Count2));
           }
        });
        PUp = (Button)findViewById(R.id.incremintationbutton1);
        txtCount = (EditText)findViewById(R.id.pi);
        txtCount.setText(String.valueOf(Count));  // Set initial value

        PUp = (Button)findViewById(R.id.incremintationbutton1);
        PUp.setOnClickListener(new OnClickListener() {
               public void onClick(View Button) {
                  Count++;
                  txtCount.setText(String.valueOf(Count));
               }
            });

}

}

修复了它，不得不将其中一个 count++ 更改为 count2++ .. 花了我一段时间，但我在喝了杯咖啡后才弄明白。
