使用DataBinding将一个数据库文本拆分为3个文本框

android {
    ...
    dataBinding {
        enabled = true
    }
}

<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <data>
        <variable
            name="data"
            type="com.example.YourDataClass" />
    </data>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@={data.content.substring(0, data.content.length() / 3)}" />

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@={data.content.substring(data.content.length() / 3, 2 * data.content.length() / 3)}" />

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@={data.content.substring(2 * data.content.length() / 3)}" />

    </LinearLayout>
</layout>

public class MainActivity extends AppCompatActivity {
    private com.example.YourDataClass data;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
        
        // 初始化数据对象
        data = new com.example.YourDataClass();
        data.setContent("这是数据库文本内容");

        // 绑定数据对象到布局
        binding.setData(data);
    }
}
