Activity转到other Activity
package cn.itcast.activitys;
import android.app.Activity;
public class MainActivity extends Activity
{
super.onCreate(Bundle savedInstanceState);
setContentView(R.layout.main);
}
public void openActivity(View v)
{
Intent intent = new Intent();
intent.setClassName("cn.itcast.activitys", "cn.itcast.activitys.OtherActivity");
// 1>intent.setClass(this,OtherActivity.class);
// 2>intent.setClassName(this, "cn.itcast.activitys.OtherActivity");
// 3>intent.setComponent(new ComponentName(this,OtherActivity.class));
// 4>Intent intent=new Intent(this,OtherActivity.class); //独立一句
/*附加数据方法一*/
intent.putExtra("name","李明");
intent.putExtra("age",5);
/*方法二*/
Bundle bundle= new Bundle();
bundle.putString("name","CC");
bundle.putInt("age",10);
intent.putExtras(bundle);
startActivity(intent);
}
OtherActivity:
package cn.itcast.activitys;
import android.app.Activity;
import android.os.Bundle;
public class OtherActivity extends Activity
{
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.otheractivity);
Intent intent = getIntent(); //用于激活它的意图对象
/*方法一*/
String name=intent.getStringExtra("name");
int age=intent.getIntExtra("age",0);
/*方法二*/
Bundle bundle = intent.getExtras();
String name=bundle.getString("name");
int age = bundle.getInt("age");
}
}
OtherActivity关闭把数据返回给MainActivity
替换startActivity();为startActivityForResult(intent,200); //请求码用来区分返回数据在哪个位置
处理得到的数据重写方法
protected void onActivityResult(int requestCode,int resultCode,Intent data)
{
String result=data.getStringExtra("result");
Toast.makeText(this,result,1).show();
}
OtherActivity:
public void closeActivity(View v)
{
Intent data = new Intent();
data.putExtra("result","mmmccc");
setResult(30,data); //结果码用来表示返回数据在哪个位置
this.finish();
}多个Activity参数传递,布布扣,bubuko.com
