Android：intent用法实例

Intent用法实例

1.无参数Activity跳转
Intentit=newIntent(Activity.Main.this,Activity2.class);
startActivity(it);

2.向下一个Activity传递数据（使用Bundle和Intent.putExtras）
Intentit=newIntent(Activity.Main.this,Activity2.class);
Bundlebundle=newBundle();
bundle.putString("name","ThisisfromMainActivity!");
it.putExtras(bundle);//it.putExtra(“test”,"shuju”);
startActivity(it);//startActivityForResult(it,REQUEST_CODE);
对于数据的获取可以采用：
Bundlebundle=getIntent().getExtras();Stringname=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）
Intentintent=getIntent();
Bundlebundle2=newBundle();
bundle2.putString("name","ThisisfromShowMsg!");
intent.putExtras(bundle2);
setResult(RESULT_OK,intent);

4.回调上一个Activity的结果处理函数（onActivityResult）
@Override

protectedvoidonActivityResult(intrequestCode,intresultCode,Intentdata){
//TODOAuto-generatedmethodstub
super.onActivityResult(requestCode,resultCode,data);
if(requestCode==REQUEST_CODE){
if(resultCode==RESULT_CANCELED)
setTitle("cancle");
elseif(resultCode==RESULT_OK){
Stringtemp=null;
Bundlebundle=data.getExtras();
if(bundle!=null)temp=bundle.getString("name");
setTitle(temp);
}
}
}
