比较 2 个文本视图值

Question

我有 2 个 TextView

Textview1 值“0”，Textview2 值“0.05”

试试这个代码

  private TextView geting_id_one, geting_id_two;



    {onCreate)
    geting_id_one = (TextView) findViewById(R.id.Textview1);
    geting_id_two= (TextView) findViewById(R.id.Textview2);

    (button Click)
   float  one = geting_id_one.getText().toString();
   float  two = geting_id_two.getText().toString();

        if (one>two){
            Toast.makeText(MainActivity.this,"TextView1 Bigger than TextView2", Toast.LENGTH_SHORT).show();
        }

        if (one>two){
            Toast.makeText(MainActivity.this,"TextView2 Bigger than TextView1", Toast.LENGTH_SHORT).show();
        }

查看错误

Answer 1

0.05 无效 Integer 值

您应该使用 double 或 float 而不是 int

示例代码

// inside oncreate()
geting_id_one = (TextView) findViewById(R.id.Textview1);
geting_id_two= (TextView) findViewById(R.id.Textview2);



// inside  button Click
double one = Double.parseDouble(geting_id_one.getText().toString());
double two =  Double.parseDouble(geting_id_two.getText().toString());

// OR

float one = Float.parseFloat(geting_id_one.getText().toString());
float two =  Float.parseFloat(geting_id_two.getText().toString());

Answer 2

您还可以通过比较两个文本视图的字符串值来比较它们的字符串值，例如：

    if (text1.getText().toString().equals(text2.getText().toString())) {
            //both are equal
    } else {
           //both have different value
    }

Answer 3

您似乎正在尝试使用 Integer.parseInt() 方法解析 float 值。请改用 Double.parseDouble("your_number_string") 或 Float.parseFloat("your_number_string")。如果需要，您可以将其转换为 integer。
