[英]Remove all items inside linearlayout
I create a linearlayout that refes to an xml item.我创建了一个引用 xml 项目的线性布局。 Inside this linearlayout i put some textview dynamically, so without taking them from the xml.
在这个线性布局中,我动态地放置了一些文本视图,因此无需从 xml 中取出它们。 Now i need to remove these textviews from the linearlayout.
现在我需要从线性布局中删除这些文本视图。 I tried this:
我试过这个:
if(((LinearLayout) linearLayout.getParent()).getChildCount() > 0)
((LinearLayout) linearLayout.getParent()).removeAllViews();
but it doesn't work.但它不起作用。 How can i do?
我能怎么做? Thanks, Mattia
谢谢,马蒂亚
Why you wrote linearLayout.getParent()
?你为什么写
linearLayout.getParent()
?
You should call this directly on LinearLayout
:您应该直接在
LinearLayout
上调用它:
linearLayout.removeAllViews();
Hi Please try this code its working for me嗨,请试试这个代码对我有用
public class ShowText extends Activity {
/** Called when the activity is first created. */
LinearLayout linearLayout;
TextView textView,textView1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textView=new TextView(this);
textView1=new TextView(this);
textView.setText("First TextView");
textView1.setText("First TextView");
linearLayout=(LinearLayout) findViewById(R.id.mn);
linearLayout.addView(textView);
