Question

我正在尝试删除在dinammically创建的表行，但是我无法获得正确的表行id，我的所有表行都具有相同的id，更多我创建它们，我的计数器设置更高的id并且所有行都得到它...我会感激任何帮助，我坚持了几天。我的方法很大，但我认为只有开始很重要。

 public void getRow(String klik, int brojkica)
{
    //db=openOrCreateDatabase(DATABASE_NAME, Context.MODE_PRIVATE, null);
    db = INF.getReadableDatabase();
    int count = 0;
    Cursor cursor3 = db.rawQuery("select id,Artikl, CIJENA from Artikli where");
    System.out.println(counterko);
    counterko++;
    tr = new TableRow(this);
    tr.setClickable(true);
    tr.setBackgroundColor(Color.GRAY);

    tr.setId(500 + counterko);

    cursor3.moveToFirst();
    final TextView sifracolumn = new TextView(this);
    sifracolumn.setId(1000 + counterko);

    sifracolumn.setPadding(5, 5, 5, 5);
    sifracolumn.setText(String.valueOf(cursor3.getInt(0)));
    sifracolumn.setGravity(Gravity.CENTER | Gravity.BOTTOM);
    sifracolumn.setTextColor(Color.BLACK);

Answer 1

使用.removeView()方法，并使用您要删除的表格行的索引或向表格行添加唯一标记，稍后根据此标记将其删除。

Answer 2

在每一行中也将id设置为标记。删除唯一行时，请使用.removeView（view.getTag（））;

Answer 3

for(int i = 0, j < table.getChildCount(); i < j; i++){
    TableRow row = (TableRow) getChildAt(i);
    if(you can check something here) {
        removeViewAt(i);
        // or...
        removeView(row);
    }
}

Answer 4

好吧，我解决了我的问题..第一个问题是

tr = new TableRow(this);

我无法将id分配给我的表行，因为id没有在我的方法中实例化它，所以首先要做的是

final TableRow tr = new TableRow(this);

然后我把onclicklistener放在我想要响应的列上并将其放入..

 artiklcolumn.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
TableRow km= (TableRow)findViewById(tr.getId());                
alert(km);

}

我获取我的对象，将其发送到警告对话框，然后从那里删除它。

 public void delete(TableRow tr2){

 tl.removeView(tr2);       

 }
