我如何随机化TextView的重力 - Android Eclipse

Question

As the title says I want to randomize the gravity of the Text in my layout(i have allready been able to randomize the color and text size of the text) The following code is rigged to an onclicklistener :

        if (check.contains("WTF")) {
                    Random crazy = new Random();
                    display.setText("WTF!!!1!");
                    display.setTextSize(crazy.nextInt(30));
                    display.setTextColor(Color.rgb(crazy.nextInt(256),crazy.nextInt(256),crazy.nextInt(256)));
                    display.setGravity(Gravity.CENTER);
                }

and there are a couple of else if and an else statement but i don't think that including them is relevant to the question.

你也可以使用Random类来做到这一点.

例:

int[] gravities = new int[4];
gravities[0] = Gravity.BOTTOM;
gravities[1] = Gravity.TOP;
gravities[2] = Gravity.LEFT;
gravities[3] = Gravity.RIGHT;

if (check.contains("WTF")) {
    Random random = new Random();
    display.setText("WTF!!!1!");
    display.setTextSize(random .nextInt(30));
    display.setTextColor(Color.rgb(random.nextInt(256),
                                  random.nextInt(256),
                                  random.nextInt(256)));
    //from 0 to gravities.length get a random number
    int randomIndex = random.nextInt(gravities.length);
    //which will be some random gravity constant
    int randomGravity = gravities[randomIndex];
    display.setGravity(randomGravity);
}
