我陷入了连接,我无法弄清问题在哪里,我有那些表

public class Themes
{
    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }

    public String ThemeName { get; set; }
    public String ThemeDesc { get; set; }
    public int ThemeImg { get; set; }
    public String ThemeCategory { get; set; }
    public String ThemeSubcategory { get; set; }
}
public class MusicItems
{
    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }

    public String Name { get; set; }
    public String Tension { get; set; }
    public String Category …

我试图改变Xamarin中TextView Drawable的颜色.

在Java中你可以这样做:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    TextView txt = (TextView) findViewById(R.id.my_textview);
    setTextViewDrawableColor(txt, R.color.my_color);
}

private void setTextViewDrawableColor(TextView textView, int color) {
    for (Drawable drawable : textView.getCompoundDrawables()) {
        if (drawable != null) {
            drawable.setColorFilter(new PorterDuffColorFilter(getColor(color), PorterDuff.Mode.SRC_IN));
        }
    }
}

我怎么能在Xamarin.Android中做这样的事情？

我试图在没有运气的情况下在 BOOT_COMPLETED 意图上运行一些代码。这是我尝试过的：
