添加多个布局动态的android [英] adding multiple layout dynamically android

问题描述

我想点击一个按钮时动态添加文本视图。我已经实现了这一点，但在写previous one.Anything错在我的code添加的时候吗？

  imGbtn.setOnClickListener（新OnClickListener（）{            公共无效的onClick（视图v）{
                INT标识= 0;
                。最终的字符串数据= textView.getText（）的toString（）;
                //childHolder.title.setText(data）;
                 LL的LinearLayout =新的LinearLayout（mContext）;
                 ll.setOrientation（LinearLayout.VERTICAL）;
                 ll.setId（ID）;
                 tvll.addView（Ⅱ）;
                // TextView的TV1 =新的TextView（mContext）;
                // tv1.setText（动态布局FTW！）;
                // ll.addView（TV1）;                LinearLayout.LayoutParams的LayoutParams =新LinearLayout.LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT）;
                layoutParams.setMargins（25，20，25，10）;
                TextView的电视=新的TextView（mContext）;
                tv.setId（ID）;
                tv.setText（数据）;
                ll.addView（电视的LayoutParams）;
                textView.setText（）;            }
        }）;
 

解决方案

以下code中的LinearLayout添加EDITTEXT的onclick

 公共类ViewOnClick延伸活动{
    LinearLayout.LayoutParams的LayoutParams;
    LL的LinearLayout;
    静态INT I;
    / **当第一次创建活动调用。 * /
    @覆盖
    公共无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;
        按钮B =（按钮）findViewById（R.id.Button01）;        b.setOnClickListener（新OnClickListener（）{            @覆盖
            公共无效的onClick（视图v）{
     LL的LinearLayout =新的LinearLayout（mContext）;
                 ll.setOrientation（LinearLayout.VERTICAL）;
                 ll.setId（ID）;
LinearLayout.LayoutParams的LayoutParams =新LinearLayout.LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT）;
                layoutParams.setMargins（25，20，25，10）;
                观点的EditText =新的EditText（ViewOnClick.this）;
                view.setText（++ 1 +意见）;
                ll.addView（视图的LayoutParams）;            }}）;
    }
}
 

I want to add text view dynamically when clicking a button . I have implemented this but when adding it over writing the previous one.Anything wrong on my code ?

imGbtn.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                int id =0;
                final String data   =   textView.getText().toString();
                //childHolder.title.setText(data);
                 LinearLayout ll = new LinearLayout(mContext);
                 ll.setOrientation(LinearLayout.VERTICAL);
                 ll.setId(id);
                 tvll.addView(ll);
                // TextView tv1 = new TextView(mContext);
                // tv1.setText("Dynamic layouts ftw!");
                // ll.addView(tv1);

                LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
                layoutParams.setMargins(25, 20, 25, 10);
                TextView tv= new TextView(mContext);
                tv.setId(id);
                tv.setText(data);
                ll.addView(tv,layoutParams);
                textView.setText("");

            }
        });

解决方案

following code add Edittext in linearlayout onclick

public class ViewOnClick extends Activity {
    LinearLayout.LayoutParams layoutParams;
    LinearLayout ll;
    static int i;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button b = (Button)findViewById(R.id.Button01);

        b.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View v) {


     LinearLayout ll = new LinearLayout(mContext);
                 ll.setOrientation(LinearLayout.VERTICAL);
                 ll.setId(id);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
                layoutParams.setMargins(25, 20, 25, 10);
                EditText view = new EditText(ViewOnClick.this);             
                view.setText(++i+" view");
                ll.addView(view, layoutParams); 

            }});
    }
}
