如何将光标内容放在textview中

Question

嗨我想将光标内容放在textview中。

即时通讯使用sqlite数据库获取当前用户的ID并在textview中显示我试图搜索但我什么都没找到 这是代码

package com.example.i.projet;

import android.database.Cursor;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.widget.EditText;

public class AfficherActivity extends AppCompatActivity {
BaseDeDonee bdd;
EditText nom , prenom , email,numt;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_afficher);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    bdd = new BaseDeDonee(this);
    int k =bdd.tempID();// to get id of corrent user
    String id = Integer.toString(k) ;
    Cursor res = bdd.afficherinfoP(id);// function return cursor 

    nom =(EditText) findViewById(R.id.nom);
    prenom=(EditText) findViewById(R.id.prenom);
    email=(EditText) findViewById(R.id.email);
    numt=(EditText) findViewById(R.id.numtele);

  if(res.getCount()<=0){
      // show message empty
  }else{
      res.moveToFirst();
      nom.setText(res.getString(res.getColumnIndex("nom")));
      prenom.setText(res.getString(res.getColumnIndex("prenom")));
      numt.setText(res.getInt(res.getColumnIndex("numero_tel")));
      email.setText( res.getString(res.getColumnIndex("profile")));

  }



}


}

Answer 1

所以我发现你的逻辑遵循以下问题：

public boolean inseloginid(int  id  ){
        SQLiteDatabase db = this.getWritableDatabase();
        Cursor res = db.rawQuery("select * from "+TABLE_Temp,null);
        ContentValues ContentVlues = new ContentValues();
        ContentVlues.put(COL_29,id);
        if(res.getCount()>0){ // I changed this condition from  <= to >
            db.delete(TABLE_Temp,null,null); // added this line
            long  result =db.insert(TABLE_Temp,null,ContentVlues);
            if (result==-1)
                return false;
            else return true ;
        }else return true;


}

原因是如果存储了先前的值，它将不会插入当前登录。更正后，如果存储了值，则清除该表并输入登录ID。在bdd.inseloginid(loggedID);之前的主要活动中调用int k = bdd.tempID();。将ID插入temp，然后用int k = bdd.tempID();拉出它。当您致电bdd.afficherinfoP(id);时，会从数据库中提取正确的数据。

使用EditText视图显示它们时：

numt.setText(res.getInt(res.getColumnIndex("numero_tel")));

返回一个字符串，因为"numero_tel"是表声明中的一个整数，所以把它变成一个字符串：

numt.setText(Integer.toString(res.getInt(res.getColumnIndex("numero_tel"))));

可能有更简单的方法可以做到这一点，但我试图保持你的逻辑完整。值得一提的是，您必须清除TABLE_temp，因为在bdd.tempID();中，您的逻辑始终会达到最高值。如果清除表格，则最高值将是登录ID。
