在MainActivity中：

public class MainActivity extends Activity {

  EditText et_name,et_sex,et_number;     @Override    protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                et_name=(EditText) findViewById(R.id.et_name);        et_sex=(EditText) findViewById(R.id.et_sex);        et_number=(EditText) findViewById(R.id.et_number);                    }

    public void onclick(View v)

    {      String name=et_name.getText().toString().trim();     String sex=et_sex.getText().toString().trim();     String number=et_number.getText().toString().trim();          if(TextUtils.isEmpty(name)&&TextUtils.isEmpty(number)&&TextUtils.isEmpty(sex))     {       Toast.makeText(this, "姓名性别手机号不能为空", 0).show();      return;     }          Intent intent=new Intent();          intent.setClass(this,MyActivity.class);          //1.1这种方式只能传递一个信息//     intent.putExtra("name", name);          //1.2     Bundle bundle=new Bundle();//用作捆绑较多的信息          bundle.putString("name", name);     bundle.putString("sex", sex);     bundle.putString("number",number);          intent.putExtras(bundle);          startActivity(intent);        }}

 

在自定义的MyActivity中（要在清单文件中注册页面）：

 

public class MyActivity extends Activity {

  TextView tv; @Override protected void onCreate(Bundle savedInstanceState) {   // TODO Auto-generated method stub  super.onCreate(savedInstanceState);  setContentView(R.layout.myactivity);  tv=(TextView) findViewById(R.id.tv);    Intent intent=this.getIntent();//返回激活这个Activity的intent    Bundle bundle=intent.getExtras();    String name=bundle.getString("name");  String sex=bundle.getString("sex");  String number=bundle.getString("number");    String text="您的信息为："+"\n"+"姓名："+name+"\n"+"性别："+sex+"\n"+"手机号："+number;    tv.setText(text); }}
