我不知道为什么它甚至无法启动活动。

这是正在推出的活动

  }else{

 }


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

 }

这是从

启动活动的地方

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


   public class Home extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

     setContentView(R.layout.homie);

     Button button1 = (Button) findViewById(R.id.button1);

     Button button2 = (Button) findViewById(R.id.button2);

     button1.setOnClickListener(new OnClickListener() {
         public void onClick(View v) {

             Intent i = new Intent(Home.this,GymFind.class);
             Home.this.startActivity(i);

         }
     });
     button2.setOnClickListener(new OnClickListener() {
         public void onClick(View v) {

             Intent i = new Intent(Home.this,EmailUs.class);
             Home.this.startActivity(i);


         }
     });
 }
   }

我非常怀疑自己会不会这样做但是如果你们愿意帮助我会非常开心。

堆栈跟踪应该在底部包含“由...引起”...或者如果您在调试器中查看它，则应该有一个“cause”变量或类似的东西。我建议只是让它崩溃，然后检查android日志 - 它肯定会打印日志中堆栈跟踪下的“由...引起的”。

问题是Android无法启动您的活动。最常见的原因是： 1.您尚未在AndroidManifest.xml中声明该活动 2. onCreate（或其他覆盖方法）中的代码抛出异常检查你的“引起的”，你会找到确切的原因。

java抛出运行时异常
