Android 在编辑文本中单击按钮时显示递增的数字。

当我点击“添加”按钮时，它会从0开始计数，并一个接一个地显示，但当我点击时 删除按钮它清除编辑文本，但当开始在添加按钮中再次单击时，它会从最后一个数字开始计数，它会停止在它上，因此我希望每次单击它时，它都会从（0）开始计数

您必须将数字变量设置为全局变量才能使代码正常工作

只要您单击按钮，它将始终初始化为1

    add.setOnClickListener(new View.OnClickListener() {


          // make it global or store in intent to retain its value after incrementing and intialize it globally and not here else again will be same case.
//            number = 1;


            public void onClick(View v) {
                // TODO Auto-generated method stub
                // random = random();
                edit.setText("" + number++); // i want when i click on it in every single time it beginning to count from( 0 )
                                   //because when i delete it and start to click again on add button it count from the last number that stop on it 


            }
        });

谢谢你的重播，但是你能给我一个这个全局变量或意图存储的ex代码吗//首先初始化，使其不包含任何ID。单击按钮后，立即复制ID并继续递增。这个变量应该在类级别。

    add.setOnClickListener(new View.OnClickListener() {


          // make it global or store in intent to retain its value after incrementing and intialize it globally and not here else again will be same case.
//            number = 1;


            public void onClick(View v) {
                // TODO Auto-generated method stub
                // random = random();
                edit.setText("" + number++); // i want when i click on it in every single time it beginning to count from( 0 )
                                   //because when i delete it and start to click again on add button it count from the last number that stop on it 


            }
        });
