工作记录(只是简单的记录下)

12-25:工作需求 需要做带多选功能的diglog--实现

//损益时间diglog
private void lossTimeDigLog(List<String> years){
    AlertDialog.Builder builder = new AlertDialog.Builder(ExpenditureDetailAct.this);
    LayoutInflater inflater = LayoutInflater.from(ExpenditureDetailAct.this);

    TextView queding = v.findViewById(R.id.queding);
    TextView quxiao = v.findViewById(R.id.quxiao);
    ListView lv1 = v.findViewById(R.id.lv1);
    lv1.setDivider(null);
    lv1.setAdapter(adap);
    final Dialog dialog = builder.create();
    dialog.show();
    dialog.getWindow().setContentView(v);//自定义布局应该在这里添加，要在dialog.show()的后面
    queding.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            List<String> list = adap.getMap();
            String tt="";
            for(String ii:list){
                tt=tt+ii+",";
            }
            if(tt.endsWith(",")){
                tt=tt.substring(0,tt.length()-1);
            }
            times = list;
            sunyiyear_tv.setText(tt);
            dialog.dismiss();
        }
    });
    quxiao.setOnClickListener(new View.OnClickListener() {
