android - 密码可见性切换崩溃应用程序，同时将依赖项升级到 27.1.0

Question

我遇到了很多与密码可见性相关的崩溃。更奇怪的是它在某些设备上崩溃，但并非全部。

我在诺基亚 5、三星 note 4 和 s7、荣耀 5C 和 9、红米 Note 4 和 4、Moto E 和 G play 以及 moto M 上进行了测试，一切正常。

Java代码

    EditText loEtPassword = (EditText) findViewById(R.id.etPassword);
    loEtPassword.setTransformationMethod(new PasswordTransformationMethod()); // Java internal class.
    loEtPassword.setOnEditorActionListener(new DoneOnEditorActionListener(loBtnLogin)); // custom class.

验证

    public static class LoginUser {
          public String lsEmail, lsPassword, lsIMEINumber, lsJsonParameter;
    }

    LoginUser loLoginUser = new LoginUser();
    loLoginUser.lsEmail = loEtEmail.getText().toString().trim();
    loLoginUser.lsPassword = loEtPassword.getText().toString();

    if (validate(loLoginUser)) {
          //cont...
    }

    private boolean validate(LoginUser foLoginUser) {

          final EditText loEtPassword = (EditText) findViewById(R.id.etPassword);

          boolean lbIsValid = true;

          if (foLoginUser.lsPassword.length() <= 0) {
              loEtPassword.setError("Please enter Password");
              loEtPassword.requestFocus();
              lbIsValid = false;
          }
          return lbIsValid;
      }

XML文件

 <android.support.design.widget.TextInputLayout

                style="@style/editTextStyle"

                android:imeOptions="actionDone"
                android:inputType="textEmailAddress" />

任何人都可以帮助如何防止这个错误？

我需要升级我的 targetSdkVersion 吗？

如果有任何替代解决方案，请提出建议，因为如果我更改目标 sdk 版本，那么我必须更新我的应用程序中的大量代码。

Answer 1

我通过简单地将 EditText(或我的 TextInputEditText)的 inputType 更改为 textPassword 来解决这个问题。所以你应该试试这个:

<EditText
    android:id="@+id/etPassword"
    ...
    android:inputType="textPassword" />

我假设您并不是要将其设置为 textEmailAddress。
