[游戏开发]Android spinner 下拉框的两种赋值方式

1、Activity 实现方法

public class AboutDeviceActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener{

    private String[] starArray={"A","B","C"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_about_device);

        initView();
    }

    private void initView() {
        Spinner mLogcatSpinner = findViewById(R.id.logcat_spinner);
        //1、 starArray ，动态设置
        ArrayAdapter<String> adapter = new ArrayAdapter<>(this, R.layout.module_spinner_item_text, starArray);
        
        // 2、res/values/arrays.xml
        //系统样式 item  R.layout.support_simple_spinner_dropdown_item
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.logcat, R.layout.support_simple_spinner_dropdown_item);
        //自定义 item 样式  R.layout.module_spinner_item_text
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.logcat, R.layout.module_spinner_item_text);
        //设置
        mLogcatSpinner.setAdapter(adapter);
        mLogcatSpinner.setOnItemSelectedListener(this);
    }

    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        switch (parent.getId()) {
            case R.id.logcat_spinner:
                String itemName = parent.getItemAtPosition(position).toString();
                Log.d(TAG, "logcat_spinner=" + itemName);
                break;
            default:
                break;
        }
    }

    @Override
    public void onNothingSelected(AdapterView<?> adapterView) {

    }
}

spinner：

                    <Spinner
                        android:id="@+id/security_module_spinner"
                        android:layout_width="0dp"
                        android:layout_height="60dp"
                        android:layout_weight="2.5"
                        android:background="@color/white"
                        android:dropDownVerticalOffset="60dp"
                        android:dropDownSelector="#0352D4"
                        android:entries="@array/logcat"
                        android:orientation="horizontal" />

1、android:entries="@array/SecurityMode"

res/values 下创建 arrays.xml 文件

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <string-array name="logcat">
        <item>Password</item>
        <item>Disable</item>
    </string-array>

</resources>   

2、module_spinner_item_text.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    style="?android:attr/spinnerItemStyle"
    android:layout_width="match_parent"
    android:layout_height="60dp"
    android:ellipsize="marquee"
    android:singleLine="true"
    android:gravity="center"
    android:textAlignment="inherit"
    android:textStyle="bold"
    android:textSize="22dp">
</TextView>
