不同位置的按钮

Question

Hello社区我开始使用android和android studio。 我对这一切都很陌生，但我在努力。

因此，这里的问题，我 具有相同的尺寸（70x70dp） 的6个按钮，我想在屏幕的不同位置，但不在同一个生成的每个时间这6个按键可以。

我已经做了它，但大部分时间，一些按钮上了其他的。 我想以某种方式限制这一点。

我已经尝试了一段时间，一些低劣的检查和所有的组合，但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 - _button2.getX()) < 10 || Math.abs(newXloc - _button4.getX()) < 10 
       || Math.abs(newXloc - _button5.getX()) < 10){

     }

     while (Math.abs(newXloc - _button.getX()) < 10 || Math.abs(newXloc - _button1.getX()) < 10 
       || 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); 
} 

任何想法？ 也许我的想法是不对的，但主要是我想要的，是每次6个按钮在不同的地方。

Answer 1

就我而言，您的问题与Intent有关。对于必须在六个新的活动创建这六个按钮和比粘贴此代码

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

代替sushi.class你必须提供新的活动的.class名字。
