我在这里有代码生成一个随机名称给定的音节点击一个行动按钮。但是作为字符串currentname生成的名称会显示在textview中。我需要让视图成为自己的类还是什么?我是来自eclipse的androidstudio的新手,所以文本视图对我来说是新的。谢谢。
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
TextView myTextView = (TextView) findViewById(R.id.view);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
class NewName {
String[] firstNameSyllables = new String[] { "mon", "fay", "shi", "zag", "blarg", "rash", "izen" };
String[] lastNameSyllables = new String[] { "malo", "zak", "abo", "wonk" };
public String createNewFirstName() {
String firstName = "";
int numberOfSyllablesInFirstName = randomRange(2, 4);
for (int i = 0; i < numberOfSyllablesInFirstName; i++) {
firstName += firstNameSyllables[randomRange(0, firstNameSyllables.length)];
}
String firstNameLetter = "";
firstNameLetter = firstName.substring(0, 1);
firstName = firstName.substring(1);
firstNameLetter = firstNameLetter.toUpperCase();
firstName = firstNameLetter + firstName;
return firstName;
}
public String createNewName() {
String firstName = "";
int numberOfSyllablesInFirstName = randomRange(2, 4);
for (int i = 0; i < numberOfSyllablesInFirstName; i++) {
firstName += firstNameSyllables[randomRange(0, firstNameSyllables.length)];
}
String firstNameLetter = "";
firstNameLetter = firstName.substring(0, 1);
firstName = firstName.substring(1);
firstNameLetter = firstNameLetter.toUpperCase();
firstName = firstNameLetter + firstName;
String lastName = "";
int numberOfSyllablesInLastName = randomRange(1, 3);
for (int j = 0; j < numberOfSyllablesInLastName; j++) {
lastName += lastNameSyllables[randomRange(0, lastNameSyllables.length)];
}
String lastNameLetter = "";
lastNameLetter = lastName.substring(0, 1);
lastName = lastName.substring(1);
lastNameLetter = lastNameLetter.toUpperCase();
lastName = lastNameLetter + lastName;
String currentName = firstName + " " + lastName;
myTextView.setText(currentName);
return currentName;
}
public int randomRange(int min, int max) {
Random random = new Random();
return random.nextInt(max - min) + min;
}
}
}
});
}
}
这是我的activity\u main.xml
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

拉你的手
NewName
类,然后创建它的示例,然后访问该方法。所以你的MainActivity
看起来像这样。我还删除了
translation
从文本属性进行检查,您可以根据您的要求进行:
