How can i change default toast message color and b

问题:

I want to create a toast message with background color is white and message color is black. My toast message is:

Toast.makeText(Logpage.this, "Please Give Feedback...", 3000).show();

I wanted to create it in another method not in onCreate().

You can create the custom toast message like below :

Toast toast = new Toast(context);
toast.setDuration(Toast.LENGTH_LONG);

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
View view = inflater.inflate(R.layout.your_custom_layout, null);
toast.setView(view);
toast.show();

One textview you can put inside the layout file and give the background and textcolor as you want.

Also you can do the following which won't need the extra custom layout file :

Toast toast = Toast.makeText(context, R.string.string_message_id, Toast.LENGTH_LONG);
View view = toast.getView();
view.setBackgroundResource(R.drawable.custom_backgrround);
TextView text = (TextView) view.findViewById(android.R.id.message);
/*Here you can do anything with above textview like text.setTextColor(Color.parseColor("#000000"));*/
toast.show();

Change Toast Colours without any additional Layouts, 2018

This is a very easy way I've found of changing the colour of the actual image background of the Toast as well as the text colour, it doesn't require any additional layouts or any XML changes:

Toast toast = Toast.makeText(context, message, duration);
View view = toast.getView();

//Gets the actual oval background of the Toast then sets the colour filter
view.getBackground().setColorFilter(YOUR_BACKGROUND_COLOUR, PorterDuff.Mode.SRC_IN);

//Gets the TextView from the Toast so it can be editted
TextView text = view.findViewById(android.R.id.message);
text.setTextColor(YOUR_TEXT_COLOUR);

toast.show();

To Change the default Toast Text Color and Background color Try Like this.

 Toast toast = Toast.makeText(MainActivity.this, "Please Give Feedback...", Toast.LENGTH_LONG);
 View view = toast.getView();

 //To change the Background of Toast
 view.setBackgroundColor(Color.TRANSPARENT);
 TextView text = (TextView) view.findViewById(android.R.id.message);

 //Shadow of the Of the Text Color
 text.setShadowLayer(0, 0, 0, Color.TRANSPARENT);
 text.setTextColor(Color.BLACK);
 text.setTextSize(Integer.valueOf(getResources().getString(R.string.text_size)));
 toast.show();

Create a layout file toast.xml as to how your toast should look as below:

<?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="@android:color/background_dark">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is a custom toast."
        android:textColor="@android:color/white"
        android:layout_gravity="center_vertical" />

</LinearLayout>

To show the toast in the java file put the below code:

public void showCustomAlert()
    {         
        Context context = getApplicationContext();
        // Create layout inflator object to inflate toast.xml file
        LayoutInflater inflater = getLayoutInflater();

        // Call toast.xml file for toast layout 
        View toast = inflater.inflate(R.layout.toast, null);

        Toast toast = new Toast(context);

        // Set layout to toast 
        toast.setView(toast);
        toast.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL,
                0, 0);
        toast.setDuration(Toast.LENGTH_LONG);
        toast.show();         
    }

You can customize android native toast by using following code

/**
 * ShowToast
 */
public class ShowToast {
    public ShowToast(Context context, String info) {
        Toast toast = Toast.makeText(context, Html.fromHtml("<font color='#e3f2fd' ><b>" + info + "</b></font>"), Toast.LENGTH_LONG);
        toast.setGravity(Gravity.TOP, 0, 0);
        toast.show();
    }
}

If you want to change the background you have to use custom layout in toast

Adding to @AndroidKiller's answer, you can also set the gravity and a custom TextView among other things like so:

Toast toast = Toast.makeText(context, context.getResources().getString(resID), Toast.LENGTH_LONG);
LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE );        
View toastView = li.inflate(R.layout.toast_hint_layout, null);
TextView text = (TextView) toastView.findViewById(R.id.hint_text_tv);
text.setText(resID);
toast.setView(toastView);
toast.setDuration(Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toastView.setBackgroundResource(R.drawable.toast_9_patch);          
toast.show();

Note, your background drawable should be a nine-patch PNG

You can even put an ImageView, and multiple TextViews in with XML like this:

<LinearLayout android:id="@+id/layout_root"
              xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:orientation="horizontal">
    <ImageView
        android:layout_width="32dp"
        android:layout_height="43dp"
        android:src="@drawable/lightbulb"
        />
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:orientation="vertical"
        >
        <TextView
            android:id="@+id/hint_text_tv"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#ccc"
            android:textSize="14dp"
            />

        <TextView
            android:id="@+id/hint_text_tv"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="(disable hints in preferences)"
            android:textColor="#555"
            android:textSize="11dp"
            />
    </LinearLayout>
</LinearLayout>

static void CustomToast(Context context, String text, int duration,
                                    @Nullable Integer backgroundColor,
                                    @Nullable Integer textColor){
        Toast t = Toast.makeText(context,text,duration);
        if (backgroundColor != null)
            t.getView()
                    .setBackgroundTintList(ColorStateList.valueOf(backgroundColor));
        if (textColor != null)
            ((TextView)t.getView().findViewById(android.R.id.message))
                    .setTextColor(textColor);
        t.show();
    }
