遇到的问题，在main中建了两个按钮，准备跳转去两个不同的界面。可是，在模拟运行的时候，总是两个按钮都跳转去了同一个界面。不知道问题出在哪里。
代码如下：
package com.example.dl;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
private Button button1,button2;//修改
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (Button)findViewById(R.id.button1);//button1 是注册
button2 = (Button)findViewById(R.id.button2);//button2 是登陆
button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setClass(MainActivity.this, MenuActivity.class);
MainActivity.this.startActivity(intent);
}
});
button2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent2 = new Intent();
intent2.setClass(MainActivity.this, LessonActivity.class);
MainActivity.this.startActivity(intent2);
}
});
}
@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;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
