如何在android中检查验证？如果intime和outtime都是空的那么Toast或两者都是空的然后通过

Question

如果 intime 和 outtime 都为空，则Toast或两者都为空，然后传递

private boolean isValidate() {
    // TODO Auto-generated method stub
    if(sp.getSelectedItem().toString().trim().length() == 0){


        Toast.makeText(getApplicationContext(), "Please Enter Name !", Toast.LENGTH_LONG).show();
        return false;
    }else{

    }

    if(etDate.getText().toString().trim().length() == 0){
        Toast.makeText(getApplicationContext(), "Please Enter Date !", Toast.LENGTH_LONG).show();


        return false;
    }else{

    }
     //both intime and out time passed either one of passed here
    if(etintime.getText().toString().trim().length() == 0){


        Toast.makeText(getApplicationContext(), "Please Enter In Time !", Toast.LENGTH_LONG).show();
        return false;
    }else{

    }
    if(etouttime.getText().toString().trim().length() == 0){

        Toast.makeText(getApplicationContext(), "Please Enter Out Time !", Toast.LENGTH_LONG).show();
        return false;
    }else{


    }
    return true;
}

使用＆amp;＆amp;条件运算符执行逻辑和在您的情况下检查两个EditTexts是否为空。

e.g。

if(editText1.getText().toString().equals("") && editText2.getText().toString().equals("")){
//show Toast here.
}
