Android如何打印正常字符串數組內的sqlite數據？

Question

你好我每個人都面臨這個問題，我太弱在DB 我寫了這段代碼來填充數據庫 現在我想複製數組裏面的數據打印出來arrayadapter 因爲我使用tabactivity，這是最好的解決辦法，我發現

public void insertIntoTable(){ 
     try{ 
      mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE,null); 
      mydb.execSQL("INSERT INTO " + TABLE + "(ID, NAME) VALUES("+Phno.getText()+",'"+PName.getText()+"')"); 

      mydb.close(); 
     }catch(Exception e){ 
      Toast.makeText(getApplicationContext(), "Error in inserting into table", Toast.LENGTH_LONG); 
     } 
    } 

，這是我想怎麼把它打印出來

mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE,null); 
     Cursor allrows = mydb.rawQuery("SELECT * FROM "+ TABLE, null); 
    String[] values = new String[] { "Iwant to put the cursor data here" }; 

     ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
       android.R.layout.simple_list_item_1, values); 
     setListAdapter(adapter); 
    }

我希望這會爲你工作

ArrayList<String> values = new ArrayList<String>(); 
mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE,null); 
     Cursor allrows = mydb.rawQuery("SELECT * FROM "+ TABLE, null); 
allrows.moveFirst() 
while(allrows.moveToNext()){ 
     String name= allrows.getString(allrows.getColumnIndex("NAME")); 
     values.add(name); 
} 
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, 
       android.R.layout.simple_list_item_1, values); 
     setListAdapter(adapter);
