android - 在 ScrollView 中连续显示 3 个按钮

Question

目前，我在 ScrollView 中显示了一个按钮列表，但是所有按钮都在左侧并在一列中向下。

我希望这些按钮显示在 3 列中，所以当我动态添加行时，一行中有 3 个按钮

这是我必须显示这些按钮的当前代码

 // Find the ScrollView
    ScrollView scrollView = (ScrollView)   
   findViewById(R.id.scrollView);

// Create a LinearLayout element
    LinearLayout linearLayout = new LinearLayout(this);
    linearLayout.setOrientation(LinearLayout.VERTICAL);

// Add Buttons


    for (int i = 0; i < 3; i++) {

        linearLayout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));


        for (int j = 0; j < 20; j++) {
            Button button = new Button(this);
            button.setText("Some text");
            linearLayout.addView(button);
        }
    }


 // Add the LinearLayout element to the ScrollView
    scrollView.addView(linearLayout);

     }

我尝试为按钮设置布局参数，但它没有改变任何东西

有什么想法吗？

谢谢

试试这个逻辑

// Find the ScrollView
    ScrollView scrollView = (ScrollView)findViewById(R.id.scrollView);

// Create a LinearLayout element
    LinearLayout linearLayout = new LinearLayout(this);
    linearLayout.setOrientation(LinearLayout.VERTICAL);
    linearLayout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));

// Add Buttons


    for (int i = 0; i < 20; i++) {
     LinearLayout linearLayoutChild = new LinearLayout(this);
     linearLayoutChild.setOrientation(LinearLayout.HORIZONTAL);
     linearLayoutChild.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));


      for (int j = 0; j < 3; j++) {
          Button button = new Button(this);
          button.setText("Some text");
          linearLayoutChild.addView(button);
        }
     linearLayout.addView(linearLayoutChild);
    }

 // Add the LinearLayout element to the ScrollView
    scrollView.addView(linearLayout);

除非需要，否则我会更喜欢 GridView 或 RecyclerView 而不是动态 View 添加
