我有一份注册表格，我需要在提交前进行验证。表单包含以下字段：名称，名字，地址，密码，用户名和密码。我需要名称有一个值，密码应至少为7个数字，密码至少为6个字符。 如何为同一个添加验证。请帮助...

试试这个：
对于Pincode验证：
else if (postalcode.length() != 7) {
invalid = true;
Toast.makeText(getApplicationContext(),
"Please enter your 7 digits postalcode", Toast.LENGTH_SHORT).show();
}
密码：
else if (password.length() < 6) {
invalid = true;
Toast.makeText(getApplicationContext(),
"Please enter atleast 6 digits password", Toast.LENGTH_SHORT).show();
}
将输入类型设为xml中的数字，以获取密码编辑文本
as：android:inputType="number"或android:inputType="phone"

试试这个..
对于.trim()字段中的每个获取文字，请使用EditText，如下所示。
String postalcode = mPostalcode.getText().toString().trim();
String password = mpass.getText().toString().trim();
为您的邮政编码和密码检查String 长度，如下所示
if(!(password.length() >= 6)){
Toast.makeText(getApplicationContext(), "password must be at least 6 characters", Toast.LENGTH_SHORT).show();
}else if(postalcode.length() != 7){
Toast.makeText(getApplicationContext(), "postalcode must be 7 numbers", Toast.LENGTH_SHORT).show();
}
