一、画布局

1.EditText：输入姓名

2.RadioGroup：里面放多个RadioButton选项

3.Button：跳转到结果页面

二、准备第二个页面

1.activity_result.xml：显示结果布局

2.TextView：三个，用来显示结果

3.ResultActivity：用来加载第二个布局

4.配置清单文件

三、在MainActivity读取输入的数据并传到ResultActivity

public void click(View v){

//【1】获取姓名

String name = et_name.getText().toString().trim();

//【2】判断是否为空

if(TextUtils.isEmpty(name)){

Toast.makeText(MainActivity.this,"请输入姓名",Toast.LENGTH_SHORT).show();

return;

}

//【3】判断用户性别

int radioButtonId = rg_group1.getCheckedRadioButtonId();

int sex = 0;

switch (radioButtonId){

case R.id.rb_man:

sex = 1;

break;

case R.id.rb_woman:

sex = 2;

break;

case R.id.rb_other:

sex = 3;

break;

}

if(sex == 0){

Toast.makeText(MainActivity.this,"请选择性别",Toast.LENGTH_SHORT).show();

return;

}

//【4】跳转到ResuleActivity

Intent intent = new Intent(MainActivity.this,ResultActivity.class);

//【5】传递数据：姓名、性别

intent.putExtra("name",name);

intent.putExtra("sex",sex);

startActivity(intent);

}

四、在Result中接受数据并显示

protected void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_resule);

TextView tv_name = findViewById(R.id.tv_name);

TextView tv_sex = findViewById(R.id.tv_sex);

TextView tv_result = findViewById(R.id.tv_result);

//【1】获取MainActivity传过来的数据

Intent intent = getIntent();

//【2】获取name，sex

String name = intent.getStringExtra("name");

int sex = intent.getIntExtra("sex",0);

//【3】将返回的数据显示到TextView上

byte[] bytes = null;

tv_name.setText(name);

try {

switch (sex) {

case 1:

tv_sex.setText("男");

bytes= name.getBytes("utf-8");

break;

case 2:

tv_sex.setText("女");

bytes= name.getBytes("gbk");

break;

case 3:

tv_sex.setText("人妖");

bytes= name.getBytes("iso-8859-1");

break;

}

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

}

//【4】计算人品的结果

int total=0;

for (byte b : bytes){

int number = b&0xff;

total+=number;

}

//【5】并显示获取得分

int score = Math.abs(total)%100;

if(score>=75){

tv_result.setText("人品得分："+score+"\n哇！人品爆棚，进入买彩票必中");

}else if(score>=50){

tv_result.setText("人品得分："+score+"\n棒棒哒，朋友多到爆");

}else if(score>=25){

tv_result.setText("人品得分："+score+"\n嗯~还可以吧，有待提高喽");

}else {

tv_result.setText("人品得分："+score+"\n咦，人品太次了，快去读读圣经吧哈哈");

}

}
