Intent用法实例
1.无参数Activity跳转
Intent it = new Intent(Activity.Main.this, Activity2.class);
startActivity(it);
2.向下一个Activity传递数据（使用Bundle和Intent.putExtras）
Intent it = new Intent(Activity.Main.this, Activity2.class);
Bundle bundle=new Bundle();
bundle.putString("name", "This is from MainActivity!");
it.putExtras(bundle); // it.putExtra(“test”, "shuju”);
startActivity(it); // startActivityForResult(it,REQUEST_CODE);
对于数据的获取可以采用：
Bundle bundle=getIntent().getExtras();
String name=bundle.getString("name");
3.向上一个Activity返回结果（使用setResult，针对startActivityForResult(it,REQUEST_CODE)启动的Activity）
Intent intent=getIntent();
Bundle bundle2=new Bundle();
bundle2.putString("name", "This is from ShowMsg!");
intent.putExtras(bundle2);
setResult(RESULT_OK, intent);
4.回调上一个Activity的结果处理函数（onActivityResult）
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode==REQUEST_CODE){
if(resultCode==RESULT_CANCELED)
setTitle("cancle");
else if (resultCode==RESULT_OK) {
String temp=null;
Bundle bundle=data.getExtras();
if(bundle!=null) temp=bundle.getString("name");
setTitle(temp);
}
}
}
