Question

Hello社区我开始使用android和android studio。我是这一切的新手，但我正在努力。

所以这是问题，我有6个相同尺寸的按钮（70x70dp）我希望这6个按钮每次都在屏幕的不同位置生成，但不能同时生成。

我已经做过了，但大多数时候，有些按钮比其他按钮高。我想以某种方式限制这一点。

我已经尝试了一段时间和一些糟糕的检查和所有组合，但到目前为止没有任何工作。

   private void changeButtonPlace(Button button) {
    Random r = new Random();
    int newXloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().width));
    int newYloc = r.nextInt(getScreenHeight() - (3 * button.getLayoutParams().height));

    if (button == _button) {
        while (Math.abs(newXloc - _button1.getX()) < 10 || Math.abs(newXloc - _button2.getX()) < 10
                || Math.abs(newXloc - _button3.getX()) < 10 || Math.abs(newXloc - _button4.getX()) < 10
                || Math.abs(newXloc - _button5.getX()) < 10){
            Log.d("myTag", "KSANA UPOLOGISA");
            newXloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().width));
        }
        while (Math.abs(newYloc - _button1.getY()) < 10 || Math.abs(newYloc - _button2.getY()) < 10
                || Math.abs(newYloc - _button3.getY()) < 10 || Math.abs(newYloc - _button4.getY()) < 10
                || Math.abs(newYloc - _button5.getY()) < 10){
            newYloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().height));
        }
    } else if (button == _button1) {
        while (Math.abs(newXloc - _button.getX()) < 10 || Math.abs(newXloc - _button2.getX()) < 10
                || Math.abs(newXloc - _button3.getX()) < 10 || Math.abs(newXloc - _button4.getX()) < 10
                || Math.abs(newXloc - _button5.getX()) < 10){
            newXloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().width));
        }
        while (Math.abs(newYloc - _button1.getY()) < 10 || Math.abs(newYloc - _button2.getY()) < 10

            newYloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().height));
        }
    } else if (button == _button2) {
        while (Math.abs(newXloc - _button.getX()) < 10 || Math.abs(newXloc - _button1.getX()) < 10
                || Math.abs(newXloc - _button3.getX()) < 10 || Math.abs(newXloc - _button4.getX()) < 10

        }

            newYloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().height));
        }
    } else if (button == _button3) {
        while (Math.abs(newXloc - _button.getX()) < 10 || Math.abs(newXloc - _button1.getX()) < 10

        }
        while (Math.abs(newYloc - _button1.getY()) < 10 || Math.abs(newYloc - _button2.getY()) < 10

            newYloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().height));
        }
    } else if (button == _button4) {

                || Math.abs(newXloc - _button2.getX()) < 10 || Math.abs(newXloc - _button3.getX()) < 10
                || Math.abs(newXloc - _button5.getX()) < 10){
            newXloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().width));
        }
        while (Math.abs(newYloc - _button1.getY()) < 10 || Math.abs(newYloc - _button2.getY()) < 10
                || Math.abs(newYloc - _button2.getY()) < 10 || Math.abs(newYloc - _button3.getY()) < 10
                || Math.abs(newYloc - _button5.getY()) < 10){
            newYloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().height));
        }
    } else if (button == _button5) {
        while (Math.abs(newXloc - _button.getX()) < 10 || Math.abs(newXloc - _button1.getX()) < 10
                || Math.abs(newXloc - _button2.getX()) < 10 || Math.abs(newXloc - _button4.getX()) < 10
                || Math.abs(newXloc - _button3.getX()) < 10){
            newXloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().width));
        }
        while (Math.abs(newYloc - _button1.getY()) < 10 || Math.abs(newYloc - _button2.getY()) < 10
                || Math.abs(newYloc - _button2.getY()) < 10 || Math.abs(newYloc - _button4.getY()) < 10
                || Math.abs(newYloc - _button3.getY()) < 10){
            newYloc = r.nextInt(getScreenWidth() - (2 * button.getLayoutParams().height));
        }
    }

    button.setX(newXloc);
    button.setY(newYloc);
}

有什么想法吗？也许我的想法不对，但主要是我想要的，每次6个按钮都在不同的地方。

就我而言，你的问题与意图有关。为此，您必须在六个新活动中创建六个按钮中的每一个，然后粘贴此代码

 public void onClick(View view) {
                        Intent i = new Intent(MainActivity.this, sushi.class);
                        startActivity(i);
                    }

代替sushi.class，您必须提供新活动的.class名称。

不同位置的按钮
