Android_自定义样式全局Toast

Android自带的toast样式不太好看,UI妹子可能会自己设计一个全局的提示,如图:

这时候就需要用到CustomView和toastUtil工具类了

一 : customView:

public class CustomToast extends Toast {

    TextView textView;
    /**
     * Construct an empty Toast object.  You must call {@link #setView} before you
     * can call {@link #show}.
     *
     * @param context The context to use.  Usually your {@link Application}
     *                or {@link Activity} object.
     */
    public CustomToast(Context context) {
        super(context);
        init(context);
    }

    private void init(Context context) {
        View view = View.inflate(context, R.layout.layout_toast,null);
        textView = (TextView) view.findViewById(R.id.content);
        setView(view);
    }

    @Override
    public void setText(CharSequence sequence){
        textView.setText(sequence);
    }

    @Override
    public void setText(int resId) {
        textView.setText(resId);
    }

}

二 :ToastUtil

public class ToastUtil extends Toast{
    private static String oldMsg;
    protected static Toast toast = null;
    private static long oneTime = 0;
    private static long twoTime = 0;

    /**
     * Construct an empty Toast object.  You must call {@link #setView} before you
     * can call {@link #show}.
     *
     * @param context The context to use.  Usually your {@link Application}
     *                or {@link Activity} object.
     */
    public ToastUtil(Context context) {
        super(context);
    }

    public static void showToast(Context context, int resId) {
        showToast(context, context.getString(resId));
    }

    public static void showToast(Context context, int resId, int gravity) {
        showToast(context, context.getString(resId), gravity, 0, 0);
    }

    public static void showToast(Context context, String s, int gravity) {
        showToast(context, s, gravity, 0, 0);
    }

    public static void showToast(Context context, int resId, int gravity, int offX, int offY) {
        showToast(context, context.getString(resId), gravity, offX, offY);
    }

    public static void showToast(Context context, String s) {
        if (TextUtils.isEmpty(s)){
            return;
        }
        if (toast == null) {
            toast = new CustomToast(context);
            toast.setText(s);
            toast.setDuration(Toast.LENGTH_SHORT);
            toast.setGravity(Gravity.CENTER,0,0);
            toast.show();
            oneTime = System.currentTimeMillis();
        } else {
            twoTime = System.currentTimeMillis();
            if (s.equals(oldMsg)) {
                if (twoTime - oneTime > Toast.LENGTH_SHORT) {
                    toast.show();
                }
            } else {
                oldMsg = s;
                toast.setText(s);
                toast.show();
            }
        }
        oneTime = twoTime;
    }


    public static void showToast(Context context, String s, int gravity, int offX, int offY) {
        if (toast == null) {
            toast = new CustomToast(context);
            toast.setText(s);
            toast.setDuration(Toast.LENGTH_SHORT);
            toast.setGravity(gravity, offX, offY);
            toast.show();
            oneTime = System.currentTimeMillis();
        } else {
            twoTime = System.currentTimeMillis();
            if (s.equals(oldMsg)) {
                if (twoTime - oneTime > Toast.LENGTH_SHORT) {
                    toast.show();
                }
            } else {
                oldMsg = s;
                toast.setText(s);
                toast.show();
            }
        }
        oneTime = twoTime;
    }
}

三:自定义样式Xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/bg_anjian_toast"
    android:gravity="center"
    android:orientation="vertical">

    <TextView
        android:id="@+id/content"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingBottom="30dp"
        android:paddingLeft="50dp"
        android:paddingRight="50dp"
        android:paddingTop="30dp"
        android:textColor="#fff"
        android:textSize="18dp" />

</LinearLayout>
