How to set Toast display time less than Toast.LENGTH_SHORT

问题

I want to display toast less than Toast.LENGTH_SHORT, as i feel its taking around 2 seconds. i want to display toast only for half second.

And what is time interval for Toast.LENGTH_SHORT and Toast.LENGTH_LONG ?

回答1:

There are only two possible values:

private static final int LONG_DELAY = 3500; // 3.5 seconds
private static final int SHORT_DELAY = 2000; // 2 seconds

Setting other values doesn't work. If duration not equals 1 (Toast.LENGTH_LONG), then duration will be SHORT_DELAY (2 seconds):

long delay = immediate ? 0 : (r.duration == Toast.LENGTH_LONG ? LONG_DELAY : SHORT_DELAY);

In sources of Toast written that

This time could be user-definable.

but I can't find way to do this.

Update: There is solution here: Set Toast Appear Length

This has worked for me

final Toast toast = Toast.makeText(getApplicationContext(), "The following message will disappear in half second", Toast.LENGTH_SHORT);
    toast.show();

    Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
           @Override
           public void run() {
               toast.cancel(); 
           }
    }, 500);

See my suggested solution here. You basically call toast.cancel() after a specified delay that is shorter than the standard toast duration.

Try this

final Toast toast = Toast.makeText(getBaseContext(), "YOUR MESSAGE",Toast.LENGTH_SHORT);
            toast.show();
            new CountDownTimer(10000, 1000)
            {
                public void onTick(long millisUntilFinished) {toast.show();}
                public void onFinish() {toast.cancel();}
            }.start();

Hope this help.. Enjoy..!!!

For noobs I've made the simplest solution - a method.

public void showToastMessage(String text, int duration){
        final Toast toast = Toast.makeText(getActivity(), text, Toast.LENGTH_SHORT);
        toast.show();
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                toast.cancel();
            }
        }, duration);
}

You should also import:

import android.os.Handler;
import android.widget.Toast;

You can call this method for example:

showToastMessage("your noob", 1000);

method above should work only in Fragment! If you want it to work in Activity, replace getActivity() with getApplicationContext() in toast message. Good luck developers!

it will work.

   public void toastMessage(final String message) {
    this.runOnUiThread(new Runnable() {
        public void run() {
            LayoutInflater myInflator = getLayoutInflater();
            View myLayout = myInflator.inflate(R.layout.custom_layout,
                    (ViewGroup) findViewById(R.id.toastlayout));
            TextView myMessage = (TextView) myLayout
                    .findViewById(R.id.label);
            myMessage.setText(message);
            Toast toast = new Toast(getApplicationContext());
            toast.setView(myLayout);
            toast.setDuration(100);
            myMessage.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL
                    | Gravity.CENTER_VERTICAL);
            toast.show();
        }
    });
}

回答7:

public void showMyToast(final Toast toast, final int delay) {
    final Timer timer = new Timer();
    timer.schedule(new TimerTask() {
        @Override
        public void run() {
            toast.show();
        }
    }, 0, 1000);
    new Timer().schedule(new TimerTask() {
        @Override
        public void run() {
            toast.cancel();
            timer.cancel();
        }
    }, delay);
}

//how to use(MainActivity.this is example ,it could be changed by yourself) and (In showMyToast(first param ,second param) method, second parameter is time what u really defined like this)

Toast toast=Toast.makeText(MainActivity.this, "MyToast Test", Toast.LENGTH_LONG);
            showMyToast(toast, 1000);

This seems to work for me (set the duration to whatever you want):

mActivity.runOnUiThread(new Runnable() {
                    public void run() {
                        Toast toast = new Toast(mActivity
                                .getApplicationContext());
                        toast.setView(layout);
                        toast.setDuration(400);
                        toast.setGravity(Gravity.TOP|Gravity.CENTER_HORIZONTAL, 0, 0);
                        toast.show();
                    }
                });
