然后当我按f8 a我得到：ZygoteInit $ methodandargscaller.run（）来源未找到

        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，重新编写清单以及我能想到的一切。它可以工作，如果我注释掉代码中的按钮的链接，并将它们留在清单中但是当我解除它们的时候我得到这些错误，请帮助!!!

Answer 1

问题是活动抛出异常。 eclipse在android SDK中查找源代码，但找不到它。

只需调试代码并找出代码抛出异常的位置。

Answer 2

解决了它，现在感觉非常愚蠢，需要在定义按钮时才开始。

activitythread.performlaunchactivity（activitythread $ activityclientrecord intent）找不到源
