Question

请尝试使用我所做的自定义字体，但我的应用程序在假设启动 LoginActivity 时崩溃。已搜索但找不到问题的解决方案。这是错误信息：

对于我的 LoginActivity：

public class LoginActivity extends Activity
{

@Override

    super.onCreate(savedInstanceState);

            // fetch the Password form database for respective user name
            String storedPassword = dbhelper.getSinlgeEntry(email1);

            // check if the Stored password matches with  Password 

            if (pass1.equals(storedPassword)) {
                Toast.makeText(LoginActivity.this, "Congrats: Login Successfull", Toast.LENGTH_LONG).show();
                Intent intent = new  Intent(LoginActivity.this,Home.class);

            }
        }


    });



    // Intent For Opening RegisterAccountActivity
    signup.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent intent = new Intent(LoginActivity.this, SignUp.class);
            startActivity(intent);
        }
    });



}
  @Override
  protected void onDestroy() {
    super.onDestroy();
    // Close The Database
    dbhelper.close();
}
}

感谢您的帮助。

Answer 1

在 LoginActivity:line 34 似乎发生了错误，但第 34 行是代码副本中的空间。

Answer 2

检查您的 MyEditText 类：

com.android.internal.os.ZygoteInit.main(ZygoteInit.java:803) 在 dalvik.system.NativeStart.main(Native Method) 原因： java.lang.RuntimeException：本机字体不能在 android.graphics.Typeface.(Typeface.java:265)

    Typeface tf = Typeface.createFromAsset(getContext().getAssets(), "fonts/Lato-Light.ttf");

您不能在此处使用原生字体。使用另一种方法。
