我在if else声明中遇到了一些问题，请支持

if (btn1.getText().toString().equals(myString[6]) &&

            {
                Toast.makeText(getBaseContext(), "test", Toast.LENGTH_SHORT).show();
            }
        }

如果执行的语句只显示“相同”。我应该从上面的代码中添加什么？

Answer 1

首先...... else if (btn1.getText().toString() == (btn2.getText().toString())....

使用.equals()来比较String ..如果是梯形而不是其他的那么使用else，如果那样你可以检查一些问题......

if else语句出错
