解决方案

您可能有一个XML文件中的错误。如果有XML错误R.java将不会产生。看看通过你的Manifest.xml和所有的布局，价值观和在res任何其他的XML文件。

一旦你发现并修正错误，清理项目。

I've began making a new project and just as I was linking my buttons to the java I noticed my R would not resolve and come to find out that my R.java file is not there. I've looked at other questions like this and they say to clean the project which I have done and it still does not work. Here is my code from the pages where it wont resolve. Thanks!

Invoice Java

package com.invoice;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class InvoiceActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);
        Thread logoTimer = new Thread(){
            public void run(){
                try{
                    sleep(5000);
                    Intent menuIntent = new Intent("com.invoice.MENU");
                    startActivity(menuIntent);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                finally{
                    finish();
                }
            }
        };
        logoTimer.start();
    }
}

Job.java

package com.invoice;


import android.app.Activity;
import android.os.Bundle;

public class Job extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.job);
    }
}

menu.java

package com.invoice;

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

public class menu extends Activity{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button job = (Button) findViewById(R.id.button4);
        job.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                startActivity(new Intent("com.invoice.job"));

            }
        });
    }

    @Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();
    }
}

解决方案

You probably have an error in an xml file. R.java will not be generated if there are xml errors. Look through you Manifest.xml and all your layout, values, and any other xml files in res.

Once you have found and fixed the error, clean the project.
