把数据库的数据放入一个传感器c1里面，然后再把c1存入list
现在我想给airT_tv3的设置文本内容为数据库的第一行数据的airT的值，我要怎么写参数？
public void run() { list=new ArrayList(); Cursor currsor=db.query("nongye",null,null,null,null,null,null); if(currsor.moveToFirst()){ do { c1=new ChuanganqiInfo(); c1.setAirT(currsor.getInt(1)); c1.setAirH(currsor.getInt(2)); c1.setLight(currsor.getInt(3)); c1.setSoilT(currsor.getInt(4)); c1.setSoilH(currsor.getInt(5)); c1.setCo2(currsor.getInt(6)); list.add(c1); }while (currsor.moveToNext()); } //ChuanganqiInfo c1=new ChuanganqiInfo(); currsor.close(); airT_tv3.setText(list.get(j).toString());//设置文本在这里 j++; if (j==currsor.getCount()){ j=0; } Toast.makeText(mContext,"刷新",Toast.LENGTH_SHORT).show(); handler.postDelayed(this,5000);} |
