Question

然后当我按 f8 a 我得到: ZygoteInit$methodandargscaller.run() source not found

                    <activity 
        android:name=".LearnCircle"
        android:label="Copy Up!">

                            <activity

        android:name=".LearnMenu"
        android:label="Copy Up!">         
    </activity>
 </application>

</manifest>

和我的代码:

package com.example.copyup;


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

public class MainActivity extends Activity {
Button start, rules, hs, learn;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    linktoxml();


start.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            Intent myIntent = new Intent(MainActivity.this, Game.class);
            MainActivity.this.startActivity(myIntent);

        }

    });
    /*
    rules.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            Intent myIntent = new Intent(MainActivity.this, Rules.class);
            MainActivity.this.startActivity(myIntent);

        }

    });

    hs.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            Intent myIntent = new Intent(MainActivity.this, Scores.class);
            MainActivity.this.startActivity(myIntent);

        }

    });

    learn.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            Intent myIntent = new Intent(MainActivity.this, LearnMenu.class);
            MainActivity.this.startActivity(myIntent);

        }

    });*/

    //show shape, take reading after 4 seconds, compare with other, if true   next, if false, end game
    //dont make it complex with time reduce yet!!
}


private void linktoxml() {
    start = (Button) findViewById(R.id.bcstart);
    rules = (Button) findViewById(R.id.brules);
    hs = (Button) findViewById(R.id.bhs);
    learn = (Button) findViewById(R.id.blearn);

}
}

我尝试过清理项目、重写 list 以及我能想到的一切。如果我在代码中注释掉指向按钮的链接并将它们留在 list 中，它会起作用但是当我取消它们时我得到这些错误，请帮助!!!

问题是 Activity 抛出异常。eclipse在android SDK中找源码，找不到。

只需调试您的代码并找出代码抛出异常的位置。
