动态图像按钮不调整大小

Question

这是我的LinearLayout中生成的按钮的arraylist，事实是，我已经在24x24中指出了大小，但是当我模仿它时，它根本没有调整大小。请帮助我，我会非常感谢它：D

 public void generate_btnRemoveContact()
    {
        LinearLayout.LayoutParams lytContactParams=new LinearLayout.LayoutParams(24,24);
        lytContactParams.weight=.5f;
        btnRemoveContact.add(new ImageButton(getApplicationContext()));
        btnRemoveContact.get(cntContact);
        btnRemoveContact.get(cntContact).setScaleType(ImageView.ScaleType.FIT_CENTER);
        btnRemoveContact.get(cntContact).setImageResource(R.drawable.ic_remove_circle_outline_red_24dp);
        btnRemoveContact.get(cntContact).setBackgroundColor(Color.TRANSPARENT);
        btnRemoveContact.get(cntContact).setTag(cntContact);
        btnRemoveContact.get(cntContact).setId(cntContact);

        btnRemoveContact.get(cntContact).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                for (int rmvCnt = v.getId(); rmvCnt < cntContact; rmvCnt++) {
                    Toast.makeText(getApplicationContext(), "you selected " + rmvCnt, Toast.LENGTH_LONG).show();
                }
            }
        });'



        lytContact.addView(btnRemoveContact.get(cntContact));

        cntContact++;

    }

根据您发布的代码，您需要在ImageButton上设置LayoutParams：

btnRemoveContact.get(cntContact).setLayoutParams(lytContactParams);
