我从这里按照教程添加行，但我遇到了问题，当我尝试添加视图时遇到问题......这是我的代码：

add_sumber_pp=(ImageView)findViewById(R.id.add_sumber_pp);

add_sumber_pp.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
        TableLayout tablelayout_penghasilan_pp=(TableLayout)findViewById(R.id.tablelayout_penghasilan_pp);
        TableRow tabel_penghasilan_pp=(TableRow)findViewById(R.id.tabel_penghasilan_pp);
        counter++;
        TextView adapter_no_dana=(TextView)findViewById(R.id.adapter_no_dana);
        TextView adapter_jenis_dana=(TextView)findViewById(R.id.adapter_jenis_dana);
        TextView adapter_jelaskan_dana=(TextView)findViewById(R.id.adapter_jelaskan_dana);
                ImageView add_pp=(ImageView)findViewById(R.id.add_pp);
                ImageView remove_pp=(ImageView)findViewById(R.id.remove_pp);
                adapter_no_dana.setText("anak "+counter);
                if(v != null) 
                { 
                     ViewGroup parentViewGroup = (ViewGroup) v.getParent();
                        if (parentViewGroup != null) {
                            parentViewGroup.removeAllViews();
                        }

                }
                tabel_penghasilan_pp.addView(adapter_no_dana);
                tabel_penghasilan_pp.addView(adapter_jenis_dana);
                tabel_penghasilan_pp.addView(adapter_jelaskan_dana);
                tabel_penghasilan_pp.addView(add_pp);
                tabel_penghasilan_pp.addView(remove_pp);

            }
        });

这是我的日志：

这是我的布局： 在此处输入图像描述

我不知道我的错在哪里..我希望有人可以帮助我解决我的问题。

对不起，这些观点

 TextView adapter_no_dana=(TextView)findViewById(R.id.adapter_no_dana);
        TextView adapter_jenis_dana=(TextView)findViewById(R.id.adapter_jenis_dana);
        TextView adapter_jelaskan_dana=(TextView)findViewById(R.id.adapter_jelaskan_dana);

是另一个布局/父级的子级，这就是问题所在。

如果要动态添加它们，则需要进行更改

TextView adapter_no_dana=new TestView(context);
        TextView adapter_jenis_dana=new TestView(context);
        TextView adapter_jelaskan_dana=new TestView(context);

在更新视图之前添加以下行

tablelayout_penghasilan_pp.removeAllViews();

是的，如果你想动态添加，你应该在你的代码中更新它

TextView adapter_no_dana=new TestView(context);
TextView adapter_jenis_dana=new TestView(context);
TextView adapter_jelaskan_dana=new TestView(context);

希望它会帮助你。
