我创建了5个类。一个类是主要活动,其余是意图活动...我直接对类实现了OnClickListener接口。运行android项目按钮事件时不起作用。源代码如下。
package com.sooraj.cbsroot;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class HomeMainActivity extends Activity implements OnClickListener {
Button btnBus, btnAbout, btnContact, btnAdmin;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_main);
btnBus = (Button) findViewById(R.id.btnBus);
btnAbout = (Button) findViewById(R.id.btnAbout);
btnContact = (Button) findViewById(R.id.btnContact);
btnAdmin = (Button) findViewById(R.id.btnAdmin);
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.btnBus) {
Intent intentBus = new Intent(HomeMainActivity.this,
BusDetails.class);
startActivity(intentBus);
}
if (v.getId() == R.id.btnAbout) {
Intent intentAbout = new Intent(HomeMainActivity.this, About.class);
startActivity(intentAbout);
}
if (v.getId() == R.id.btnContact) {
Intent intentContact = new Intent(HomeMainActivity.this,
Contact.class);
startActivity(intentContact);
}
if (v.getId() == R.id.btnAdmin) {
Intent intentAdmin = new Intent(HomeMainActivity.this,
AdminLogin.class);
startActivity(intentAdmin);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.home_main, menu);
return true;
}
}
