Android EditText OnClickListener问题

Question

我有销售申请.当用户单击EditText时,弹出计算器想要显示.在我的情况下,当用户双击EditText onClickLister它时,它会显示弹出计算器.

这是myEditText

    final EditText txtQty = new EditText(this);
            txtQty.setHeight(1);
            if(productList.get(i).getQty() != 0.00){
                txtQty.setText(Double.toString(productList.get(i).getQty()));
            }
            txtQty.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,42));
            txtQty.setTextSize(9);
            txtQty.setId(i);
            txtQty.setHint("0");
            txtQty.setClickable(true);
            txtQty.setSelected(true);
            txtQty.setSelectAllOnFocus(true);
            txtQty.setInputType(InputType.TYPE_NULL);
            tr.addView(txtQty); 

这是我的代码:

   txtQty.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    String productCode= txtCode.getText().toString();
                    double price = getProductPrice(productCode).getPrice();
                    txtPrice.setText(""+price);

                    if(invPriceEdit.equals("3")){ 
                        if(editPrice.getText().toString().equals("") || editPrice.getText().toString().equals("0.00") || editPrice.getText().toString().equals("0") || editPrice.getText().toString().equals("0.0")){
                            txtPrice.setText(""+ price);
                            editPrice.setText("" +price);
                        }else{
                            String ePrice = editPrice.getText().toString();
                            editPrice.setText("" +ePrice);
                        }
                    }


                        keyAmount = new StringBuffer();
                        if(keyAmount.length() > 0){
                            keyAmount.delete(0, keyAmount.length());
                        }

                        int[] origin = new int[2];
                        v.getLocationOnScreen(origin);
                        final int xVal = origin[0];

                        lp.x = xVal;
                        lp.y = yVal;

                }
                }

这是销售代表的一个问题.他们希望双击每一个产品clcik.

我想在用户选择textEditor时显示弹出计算器.(不要双击).

这是我的代码:

       final EditText txtQty = new EditText(this);
            txtQty.setHeight(1);
            if(productList.get(i).getQty() != 0.00){
                txtQty.setText(Double.toString(productList.get(i).getQty()));
            }
            txtQty.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,42));
            txtQty.setTextSize(9);
            txtQty.setId(i);
            txtQty.setHint("0");
            txtQty.setInputType(InputType.TYPE_NULL);
            tr.addView(txtQty); 

问题是:

`TableLayout包含产品信息列表,当用户点击Qty后弹出计算器输入值后,它将清除那一行上的EditText数量&它转到第一行EditText'

Answer 1

为什么要添加onClickEventEditText,

对于EditText,onFocusChangeListener()只要edittext获得焦点,就可以使用它来激活对话框.在onFocusChangeListener()你可以检查是否EditText正在获得焦点或失去焦点.

Answer 2

我已经使用了setOnTouchListener

    disValEdit.setOnTouchListener(new OnTouchListener() {
                public boolean onTouch(View v, MotionEvent event) {
                    if(event.getAction() == MotionEvent.ACTION_UP) { } });
