不带数据和返回的Activity跳转，返回activity跳转
public class MainActivity extends Activity {
Button bt;
Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context = this; //存放当前Activity的实例
setContentView(R.layout.activity_main);
bt = (Button)findViewById(R.id.bt);
bt.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
setContentView(R.layout.second);
Intent intent = new Intent(context,Second.class); //设置此Activity跳转到另一个Activity
startActivity(intent); //启动目标Activity
}
});
}
}
public class Second extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
Intent intent = getIntent(); //接受起始Activity传递过来的Activity
}
