联系列表视图，在android上选择所有选项和搜索选项我已经尝试了很多方法，但无论是找到名单的列表视图，电话号码和每个人的复选框，还是一个全选按钮和搜索选项

public void onTextChanged(CharSequence s,int start, int before, int count)
                    {
                        textlength = et.getText().length();
                    //  et.setText(textlength);
                        if(et.getText().toString().equalsIgnoreCase("helloo")){
                        //  Toast.makeText(getApplicationContext(),"jd",1000).show();
                            for (int i = 0; i < name1.size(); i++)
                            {
                            if (textlength <= name1.size())
                            {
                                Toast.makeText(getApplicationContext(),"searching.....inside",1000).show();
                            if(et.getText().toString().equalsIgnoreCase((String)((CharSequence) name1).subSequence(0,textlength)))
                            {
                            //  array_sort.addAll(name1);
                                                                                                                            }

                                if(et.getText().toString().equalsIgnoreCase(

                                }

                                }
                            lv.setAdapter(new ArrayAdapter<String>

我遇到了同样的问题。最后我用这段代码解决了。希望它会帮助你:)）

    //layout function
    public void lay_out(List<String> exp1,int k){
    LayoutInflater layoutInflater = 
                (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                container.removeAllViews();
                for(int i=0;i<exp1.size();i++){

                    TextView tv=(TextView)addView.findViewById(R.id.textView1);
                    final CheckBox cb=(CheckBox) addView.findViewById(R.id.checkbox1);
                    if(k==0)
