Question

我的朋友为我制作了一个工具栏代码，它必须在操作栏下。如何将它添加到主ml布局以及主java活动？

public class Fencing {

public static void main(String[] args) {

  double totalFencingUnits = 0;
  double fencingUnitWeight = 2.5;

    boolean b = true;
    double corner = 0;
    double core = 0;
    double side = 0;
    int i = 0;
    int j = 0;
    int[][] map = { 
        { 0, 1, 1, 0 }, 
        { 1, 1, 1, 1 }, 
        { 1, 1, 1, 1 }, 
        { 1, 1, 0, 1 } 
    };


  for (i = 0; i < map.length; i++) {
        for (j = 0; j < map[0].length; j++) {

            if (map[i][j] != 1 && map[i][j] != 0) {
                b = false;
                System.out.println("--> An invalid value of " + map[i][j] + " was found at " + i + "," + j);
            }

          if ( map[i][j] == 1){

            //do the outer corners
            if((i == 0 && (j == 0 || j == map.length - 1)) || (i == map.length - 1 && (j == 0 || j == map.length - 1))){
              System.out.println("A corner " + map[i][j] + " was found at " + i + "," + j);
              totalFencingUnits += 2;
              switch (2*i - j  ) {
                case -3:  
                  totalFencingUnits += map[i][j - 1] > 0?0:1;
                  totalFencingUnits += map[i + 1][j] > 0?0:1;
                 break;
                case 6:  
                 totalFencingUnits += map[i - 1][j] > 0?0:1;
                 totalFencingUnits += map[i ][j + 1] > 0?0:1;
                 break;
                case 0:  
                 totalFencingUnits += map[i][j + 1] > 0?0:1;
                 totalFencingUnits += map[i +1 ][j] > 0?0:1;
                 break;
                case 3:  
                 totalFencingUnits += map[i - 1][j] > 0?0:1;
                 totalFencingUnits += map[i ][j - 1] > 0?0:1;
                 break;
                default:
                break;
              }
            }
            //do the outer sides
            else if((i == 0 && (j != 0 && j != map.length - 1)) || (i == map.length - 1 && (j != 0 && j != map.length - 1))
              || (j == 0  && (i != 0 && i != map.length - 1)) || (j == map.length - 1 && (i != 0 && i != map.length - 1))){
              System.out.println("A side " + map[i][j] + " was found at " + i + "," + j);
              totalFencingUnits ++;
              if ( i == 0){
                totalFencingUnits += map[i][j - 1] > 0?0:1;
                 totalFencingUnits += map[i + 1][j] > 0?0:1;
                totalFencingUnits += map[i][j +  1] > 0?0:1;
              }
              if (i == map.length - 1){
                totalFencingUnits += map[i][j - 1] > 0?0:1;
                 totalFencingUnits += map[i -1 ][j] > 0?0:1;
                totalFencingUnits += map[i][j +  1] > 0?0:1;
              }
              if ( j == 0){
                totalFencingUnits += map[i - 1][j] > 0?0:1;
                 totalFencingUnits += map[i][j + 1] > 0?0:1;
                totalFencingUnits += map[i + 1][j ] > 0?0:1;
              }
              if ( j == map.length - 1){
                totalFencingUnits += map[i - 1][j] > 0?0:1;
                 totalFencingUnits += map[i][j - 1] > 0?0:1;
                totalFencingUnits += map[i + 1][j ] > 0?0:1;
              }

            }
            //now do the internals blocks
            else {

              System.out.println("An internal " + map[i][j] + " was found at " + i + "," + j);
              totalFencingUnits += map[i - 1][j] > 0?0:1;
                 totalFencingUnits += map[i][j - 1] > 0?0:1;
                totalFencingUnits += map[i ][j + 1] > 0?0:1;
              totalFencingUnits += map[i + 1][j ] > 0?0:1;

            }

          }
        }
    }

    if (b == false && i == 4) {
        System.out.println("The map is invalid");
        return;
    } else {
        System.out.println("Map is valid");
        System.out.println("TOTAL FENCING UNITS: " + totalFencingUnits );
        System.out.println("TOTAL FENCING WEIGHT: " + totalFencingUnits * fencingUnitWeight);
    }



    }
}

但现在我还没有和他联系。如何将它添加到主xml以及主java活动？

请帮帮我们！

您需要创建一个自定义工具栏（最好是单独的xml文件，因为我们可以重复使用它）并使用include标记将其包含在您的xml文件中。

<include
        layout="@layout/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

这里＆＃39;工具栏＆＃39;是布局文件夹中的xml文件（包含工具栏设计）。

如果您要删除操作栏，则可以设置“父母”＆＃39; style.xml的属性为＆＃39; Theme.AppCompat.Light.NoActionBar＆＃39;

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
