一个简单的Toast实用工具类!
不管是为了统一风格还是为了使用Toast更好看,或者使用Toast更方便,自己经过几番改进,写出了
下面的Toast实用工具类,与大家分享.请大家指教:
1.方法经过了多次重构,应该没有什么多余的代码.这要多感谢曾经给过多帮助的重构一书.
2.有使用自定义布局的示例.
3.代码显而易见,所以就没有多余的注释了.
先上代码:
public class ToastUtils { private static int GRAVITY = Gravity.CENTER; public static void showLong(Context context, String message) { show(context, message, Toast.LENGTH_LONG); } public static void showShort(Context context, String message) { show(context, message, Toast.LENGTH_SHORT); } public static void showLong(Context context, int textId) { show(context, textId, Toast.LENGTH_LONG); } public static void showShort(Context context, int textId) { show(context, textId, Toast.LENGTH_SHORT); } public static void show(Context context, String text, int duration) { Toast toast = Toast.makeText(context, text, duration); toast.setGravity(GRAVITY, 80, 80); toast.show(); } public static void show(Context context, int textId, int duration) { Toast toast = Toast.makeText(context, textId, duration); toast.setGravity(GRAVITY, 80, 80); toast.show(); } public static void showSuccess(Context context, int textId) { showIconToast(context, textId, R.drawable.ic_success, R.color.holo_blue); } public static void showFailure(Context context, int textId) { showIconToast(context, textId, R.drawable.ic_failure, R.color.warn); } public static void showIconToast(Context context, int textId, int iconId, int colorId) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.toast, null); ((TextView) layout).setText(textId); ((TextView) layout).setTextColor(context.getResources().getColor( colorId)); ((TextView) layout).setCompoundDrawablesWithIntrinsicBounds(iconId, 0, 0, 0); Toast toast = new Toast(context); toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0); toast.setDuration(Toast.LENGTH_SHORT); toast.setView(layout); toast.show(); } }
再上自定义Toast的布局文件:R.layout.toast
<?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/toast_bg" android:drawablePadding="20dp" android:gravity="center" android:padding="20dp" android:text="success" android:textSize="16sp" android:textStyle="bold" />
