人品计算器demo

最近在玩小游戏的时候看到人品计算器 感觉不难做就试了下，当然做的很简陋~~





下面是代码：MainActivity 获取姓名，性别传到下个界面去

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

private EditText et_name;
private RadioGroup rg_sex;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
et_name = (EditText) findViewById(R.id.et_name);
rg_sex = (RadioGroup) findViewById(R.id.rg_sex);
Button bt_calcu = (Button) findViewById(R.id.bt_calcu);
assert bt_calcu != null;
bt_calcu.setOnClickListener(this);

}

@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.bt_calcu:
String name = et_name.getText().toString().trim();
if (TextUtils.isEmpty(name)) {
Toast.makeText(this, "姓名不能为空", Toast.LENGTH_SHORT).show();
return;
}
int checkedRadioButtonId = rg_sex.getCheckedRadioButtonId();
int sex = 0;
switch (checkedRadioButtonId) {
case R.id.rb_man:
sex = 1;
break;
case R.id.rb_woman:
sex = 2;
break;
case R.id.rb_taijian:
sex = 3;
break;
}
if (sex == 0) {
Toast.makeText(this, "请选择性别", Toast.LENGTH_SHORT).show();
return;
}

Intent intent = new Intent(this, ResultActivity.class);
intent.putExtra("name", name);
intent.putExtra("sex", sex);
startActivity(intent);

break;
}
}
}

这是布局代码

<EditText
android:id="@+id/et_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="请输入您的姓名" />

<RadioGroup
android:id="@+id/rg_sex"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">

<RadioButton
android:id="@+id/rb_man"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="男"

/>

<RadioButton
android:id="@+id/rb_woman"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:text="女" />

<RadioButton
android:id="@+id/rb_taijian"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="人妖" />

</RadioGroup>

<Button
android:id="@+id/bt_calcu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="计算"
android:textSize="25sp" />

ResultActivity ：显示测试结果，人品是随机数决定的（这样最简单：））

public class ResultActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_result);
TextView tv_name = (TextView) findViewById(R.id.tv_name);
TextView tv_sex = (TextView) findViewById(R.id.tv_sex);
TextView tv_rp = (TextView) findViewById(R.id.tv_rp);

Intent intent = getIntent();
String name = intent.getStringExtra("name");
int sex = intent.getIntExtra("sex", 0);

tv_name.setText("姓名：" + name);
switch (sex) {
case 1:
tv_sex.setText("性别：男");
break;
case 2:
tv_sex.setText("性别：女");
break;
case 3:
tv_sex.setText("性别：太监");
break;
}

int random = (int) (Math.random() * 10);
switch (random) {
case
4000
0:
tv_rp.setText("您的人品很差！！！");
break;
case 1:
case 2:
case 3:
tv_rp.setText("您的人品一般般哦！");
break;
case 4:
case 5:
case 6:
tv_rp.setText("您的人品还可以哦！");
break;
case 7:
case 8:
case 9:
tv_rp.setText("您的人品非常棒哦！");
break;
default:
}
}
}

布局代码

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="姓名：张三"
android:textSize="25sp"
android:id="@+id/tv_name"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="性别：男"
android:textSize="25sp"
android:id="@+id/tv_sex"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="您的人品非常好！"
android:textSize="25sp"
android:id="@+id/tv_rp"
/>

写完测试的时候一直崩溃，半天都找不到错误，做后才发现是ResultActivity没注册~
