        lLayout =新的LinearLayout [8];
        的for（int i = 0; I＆LT; lLayout.length;我++）{
            lLayout [I] =新的LinearLayout（本）;
            lLayout [I] .setId（ⅰ）;
            lLayout [I] .setOrientation（LinearLayout.HORIZONTAL）;

                lLayout [I] .setBackgroundColor（Color.GREEN）;
            }其他{

            }
            parentLayout.addView（lLayout [I]）;

解决方案

您需要设置的LayoutParams，尝试添加这样的：

  lLayout [I] .setLayoutParams（新的LayoutParams（LayoutParams.MATCH_PARENT，LayoutParams.WRAP_CONTENT））;
 

I'm trying to add LinearLayouts dynamically but it's just not working. I think I just need another set of eyes to look it over. Can anyone help me?

LinearLayout parentLayout = (LinearLayout)findViewById(R.id.parentLayout);
        lLayout = new LinearLayout[8];
        for(int i = 0; i < lLayout.length; i++) {
            lLayout[i] = new LinearLayout(this);
            lLayout[i].setId(i);
            lLayout[i].setOrientation(LinearLayout.HORIZONTAL);
            if(i%2 == 0) {
                lLayout[i].setBackgroundColor(Color.GREEN);
            } else {
                lLayout[i].setBackgroundColor(Color.MAGENTA);
            }
            parentLayout.addView(lLayout[i]);
        }

解决方案

You need to set LayoutParams, try adding this:

lLayout[i].setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));
