Android学习笔记之Intent

Posted 2020-06-18 喜爱糖葫芦

1.Intent指定启动目标组件

2.Intentfilter描述基本组件所在地址

3.其他包引入资源文件时记得引入R所在的包

package com.jikexueyuan.intent;


import com.jiahemeikang.helloandroid.R;
import android.app.Activity;
import android.os.Bundle;

public class Aty2 extends Activity{

    public Aty2() {
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onCreate(Bundle e) {
        super.onCreate(e);
        setContentView(R.layout.aty2);
    }
}

 

R的包

将做好的资源文件加入Android activty加入Android Manifest
