这是相对布局视图，它是动态创建的，如下所示：

... 所以我的问题是如何从这些动态元素中获取值并执行一些计算以在textview上显示结果，textview也是动态创建的。先谢谢你们!!

    public void goButtonClicked(View view) {
    maalContainer.removeAllViews();
    int numberofPlayersTolayout = (Integer) Integer.parseInt((String) numberOfPlayers.getSelectedItem());

    LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);

    for (int i = 0; i < numberofPlayersTolayout; i++) {
        View dynamicEntryView = inflater.inflate(R.layout.player_entry_item, null);
        maalContainer.addView(dynamicEntryView, params);
    }

}

}

Answer 1

for (int i = 0; i < maalContainer.getChildCount(); i++) {
    View view = maalContainer.getChildAt(i);

    EditText ed_item = (EditText) view
            .findViewById(R.id.edittext1);
    EditText ed_value = (EditText) view
            .findViewById(R.id.edittext2);
    EditText ed_value1 = (EditText) view
            .findViewById(R.id.edittext3);

    ed_item.getText().toString().trim();
    ed_value.getText().toString().trim();
    ed_value1.getText().toString().trim();
}

Answer 2

无需分配/获取任何视图的ID，但最好的方法是遍历LinearLayout的子视图：

int childcount = myLinearLayout.getChildCount();
for (int i=0; i < childcount; i++){
      View v = myLinearLayout.getChildAt(i);
    // do whatever you would want to do with this View
}

Answer 3

这里有一些事情：

您不应该使用Application Context来获取LayoutInflater。你应该从Activity Context获得，否则你的主题和风格将不受尊重。
您不应该使用null作为第二个参数进行充气（除非在您不知道View的父级的特殊情况下）。只需将android:layout_width="match_parent"和android:layout_height="wrap_content"属性放在player_entry_item.xml中，通货膨胀就会受到尊重。
将EditText个对象存放在通货膨胀时作为私人阵列。

话虽如此，我建议修改：

private EditText[] mEditTextPlayers;

public void goButtonClicked(View view) {
    maalContainer.removeAllViews();
    int numPlayers = Integer.parseInt((String) numberOfPlayers.getSelectedItem());

    LayoutInflater inflater = LayoutInflater.from(view.getContext());
    mEditTextPlayers = new EditText[numPlayers];

    for (int i = 0; i < numPlayers; i++) {
        //Pass the parent as the second parameter to retain layout attributes
        mEditTextPlayers[i] = inflater.inflate(R.layout.player_entry_item, maalContainer, false);
        maalContainer.addView(dynamicEntryView);
    }
}

Answer 4

     public void goButtonClicked(View view) {
         int numberofPlayersTolayout =       Integer.parseInt(numberOfPlayers.getSelectedItem().toString());
        LayoutInflater inflater = (LayoutInflater)  getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT,  LayoutParams.WRAP_CONTENT);
        maalContainer.removeAllViews();

        maalText = new EditText[numberofPlayersTolayout];
        points = new EditText[numberofPlayersTolayout];
        result = new TextView[numberofPlayersTolayout];
        for (int i = 0; i < numberofPlayersTolayout; i++) {
            View dynamicEntryView = inflater.inflate(R.layout.player_entry_item, null);
            maalContainer.addView(dynamicEntryView, params);
            TextView playerName = (TextView) dynamicEntryView.findViewById(R.id.player_name_textview);
            playerName.setText("Player :" + (i + 1));

            maalText[i] = (EditText) dynamicEntryView.findViewById(R.id.player_item_edittext_maal);
            points[i] = (EditText) dynamicEntryView.findViewById(R.id.player_item_edittext_point);
            result[i] = (TextView) dynamicEntryView.findViewById(R.id.player_item_textview_result);
}

Answer 5

您可以使用视图的getId()和setId()方法来完成此操作。

   dynamicEntryView.setId(i);

并通过获取

访问以下视图

   dynamicEntryView.getId(i);

仅使用一个ID。它将根据玩家数量循环。希望它会对你有所帮助。 @ user2731584
