如何在android上添加行
如何在android上添加行
提问于 2013-11-11 12:50:54
我按照here的教程来添加行，但是我遇到了这个问题，当我试图添加视图时，我遇到了问题……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logcat：

打扰一下，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/父级的子节点，这就是问题所在。
如果您想要动态添加它们，则需要进行如下更改
TextView adapter_no_dana=new TestView(context);
TextView adapter_jenis_dana=new TestView(context);
TextView adapter_jelaskan_dana=new TestView(context);Stack Overflow用户

在更新视图之前添加以下行
tablelayout_penghasilan_pp.removeAllViews();是，如果要动态添加，则应在代码中对其进行更新
TextView adapter_no_dana=new TestView(context);
TextView adapter_jenis_dana=new TestView(context);
TextView adapter_jelaskan_dana=new TestView(context);希望能对你有所帮助。
