我在" R.Id.button1"说" - Id无法解析或不是字段 - button1无法解析或不是字段。"
package com.example.chopbuilderfordrums;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class ExerciseList extends Activity implements View.OnClickListener {
Button button1;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_exercise_list);
button1 = (Button)findViewById(R.Id.button1);
button1.setOnClickListener(this);
}
private void button1Click()
{
startActivity(new Intent("com.example.chopbuilderfordrums.LaunchWarmupsList" ));
}
public void onClick (View v) {
switch (v.getId())
{
case R.Id.button1:
button1Click();
break;
}
}
}
