package com.huawei;

import android.app.Activity;

import android.content.ComponentName;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

public class Test extends Activity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        Button btn = (Button) findViewById(R.id.btn);

        btn.setOnClickListener(new OnClickListener() {






@Override



public void onClick(View v) {



//组件名称，第一个参数是包名，也是主配置文件Manifest里设置好的包名第二个是类名，要带上包名



ComponentName com = new ComponentName(“com.huawei”, “com.huawei.Test1”);



Intent  intent = new Intent();



//设置部件



intent.setComponent(com);


       
Test.this.startActivity(intent);



  }



});
