How to display Toast at center of screen

问题:

In Android I want to display a toast message at the bottom of the screen, I tried this:

Toast.makeText(test.this,"bbb", Toast.LENGTH_LONG).show();

It doesn't work, how do I do it correctly?

回答1:

To display the Toast in center of the screen.

Toast toast = Toast.makeText(test.this,"bbb", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();

回答2:

Positioning your Toast

A standard toast notification appears near the bottom of the screen, centered horizontally. You can change this position with the setGravity(int, int, int) method. This accepts three parameters: a Gravity constant, an x-position offset, and a y-position offset.

For example, if you decide that the toast should appear in the top-left corner, you can set the gravity like this:

toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);

If you want to nudge the position to the right, increase the value of the second parameter. To nudge it down, increase the value of the last parameter.

Layout file for custom toast

<ImageView
android:id="@+id/image"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="5dp" />

<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textColor="#000" />

.java file for custom toast on button's click event

public class MainActivity extends Activity {

private Button button;

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    button = (Button) findViewById(R.id.buttonToast);

    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            // get your custom_toast.xml ayout
            LayoutInflater inflater = getLayoutInflater();

            View layout = inflater.inflate(R.layout.custom_toast,
              (ViewGroup) findViewById(R.id.custom_toast_layout_id));

            // set a dummy image
            ImageView image = (ImageView) layout.findViewById(R.id.image);
            image.setImageResource(R.drawable.ic_launcher);

            // set a message
            TextView text = (TextView) layout.findViewById(R.id.text);
            text.setText("Button is clicked!");

            // Toast...
            Toast toast = new Toast(getApplicationContext());
            toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
            toast.setDuration(Toast.LENGTH_LONG);
            toast.setView(layout);
            toast.show();
        }
    });
}

}

Toast toast = new Toast(context);
        toast.setGravity(Gravity.FILL_HORIZONTAL | Gravity.BOTTOM, 0, 0);
toast.show();

回答5:

In Xamarin.Android, this displays toast at center of screen:

            Toast toast = Toast.MakeText(ApplicationContext, "bbb", ToastLength.Long);
            toast.SetGravity(GravityFlags.Center, 0, 0);
            toast.Show();

The below code worked for me.

Toast.makeText(this, "Toast in center", Toast.LENGTH_SHORT).setGravity(Gravity.CENTER,0,0).show();
