如何将数据从Activity传递到CustomView？

public class CustomView extends View {
    private String data;

    public CustomView(Context context, String data) {
        super(context);
        this.data = data;
    }
    
    // 其他代码...
}

String data = "Hello CustomView";
CustomView customView = new CustomView(this, data);

public class CustomView extends View {
    private String data;

    public CustomView(Context context) {
        super(context);
    }
    
    public void setData(String data) {
        this.data = data;
        // 数据更新后，可以调用invalidate()方法触发重绘
        invalidate();
    }
    
    // 其他代码...
}

String data = "Hello CustomView";
customView.setData(data);

<resources>
    <declare-styleable name="CustomView">
        <attr name="data" format="string" />
    </declare-styleable>
</resources>

public class CustomView extends View {
    private String data;

    public CustomView(Context context, AttributeSet attrs) {
        super(context, attrs);
        TypedArray typedArray = context.obtainStyledAttributes(attrs, R.styleable.CustomView);
        data = typedArray.getString(R.styleable.CustomView_data);
        typedArray.recycle();
    }
    
    // 其他代码...
}

<com.example.CustomView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:data="Hello CustomView" />
