我用两个按钮创建了这个活动
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.content.Intent;
public class SelectOption extends Activity{
Button bu1,bu2,bu3;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.option_main);
bu1 = (Button)findViewById(R.id.button1);
bu2 = (Button) findViewById(R.id.button2);
bu1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent myintent1 = new Intent(SelectOption.this, CheckBalance.class);
startActivity(myintent1);
}
});
bu2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent myintent2 = new Intent(SelectOption.this, CheckAvailability.class);
startActivity(myintent2);
}
});
还有 2 个名为 CheckBalance.java 和 CheckAvailability.java 的活动。但是当我运行程序时,它什么也没有发生。有谁知道这有什么问题?
