删除 app:buttonColor 行并重试
或
您可以按照以下步骤操作
1. prest Ctrl+Alt+Shift+S
2. Select project
3. Change gradle Version to -> 3.3
4. change Android PLugin version to -> 2.3.3
对我有用
还有可用的备用库https://github.com/jd-alexander/android-flat-button
您无法保存信息。hoang8f.widget.FButton 在简单的按钮中使用库提供的按钮，如下所示。
info.hoang8f.widget.FButton btnSignIn, btnSignUp;
btnSignIn = (FButton) findViewById(R.id.btnSignIn)
您实际上不需要完整的包，我只是将其用作参考，只需导入包即可
最新更新：
我想我找到了答案，虽然我还没有测试它，但它是最近的一次提交，人们已经证明它有效，请参阅 jd-alexander 的 评论，
https://github.com/hoang8f/android-flat-button/issues/41#issuecomment-350491965
此外，请在此处查看 hoang8f 的平面 android 按钮的修改后的回购协议

旧 POST 从这里开始
我相信您正在关注 youtube 上的 "Eat-it" 应用教程。我遇到了同样的挑战，我也怀疑它与
有关
info.hoang8f.widget.FButton
我尝试的是进入我的 gradle 文件（应用程序）并注释掉对该 api 的调用，还将它在应用程序中的每一次出现都从信息更改为按钮。hoang8f.widget.FButton 这样我就可以在没有按钮的情况下工作，并且不会再出现错误。
同时检查您的 styles.xml 文件，如果 "Theme" 有错误，如果有 none，请尝试检查代码。如果您的任何文件抛出任何错误，它应该会告诉您。
如果其他所有方法都失败，请检查此处
如果您使用 android studio v3，您可能需要更改 gradle 版本，您的 gradle 版本也会显示为 3，因此您可以在 [=56] 中降级=]（项目）文件，如：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
我是开发新手 Android。在编写我的代码和 运行 调试器后，我的应用程序无法打开并显示 "Unfortunately App has stopped"。

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

这是我的MainActivity.java
public class MainActivity extends AppCompatActivity {
Button btnSignIn,btnSignUp;
TextView txtSlogan;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnSignIn = (Button)findViewById(R.id.btnSignIn);
btnSignUp = (Button)findViewById(R.id.btnSignUp);
txtSlogan = (TextView)findViewById(R.id.txtSlogan);
Typeface face = Typeface.createFromAsset(getAssets(),"fonts/Nabila.ttf");
txtSlogan.setTypeface(face);
btnSignIn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
}
});
btnSignUp.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
}
});
}
}
有人知道我的问题出在哪里吗？我需要解决它，因为这是我最后一年的项目。
<info.hoang8f.widget.FButton
android:id="@+id/btnSignUp"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:layout_weight="1"
android:text="Sign Up"
android:textColor="@android:color/white"
// app:buttonColor="@color/btnSignUp"
app:cornerRadius="4dp"
app:shadowColor="@android:color/black"
app:shadowEnabled="true" />
删除 app:buttonColor 行并重试
或
您可以按照以下步骤操作
1. prest Ctrl+Alt+Shift+S
2. Select project
3. Change gradle Version to -> 3.3
4. change Android PLugin version to -> 2.3.3
对我有用
还有可用的备用库https://github.com/jd-alexander/android-flat-button
您无法保存信息。hoang8f.widget.FButton 在简单的按钮中使用库提供的按钮，如下所示。
info.hoang8f.widget.FButton btnSignIn, btnSignUp;
btnSignIn = (FButton) findViewById(R.id.btnSignIn)
您实际上不需要完整的包，我只是将其用作参考，只需导入包即可

旧 POST 从这里开始
我相信您正在关注 youtube 上的 "Eat-it" 应用教程。我遇到了同样的挑战，我也怀疑它与
有关info.hoang8f.widget.FButton
我尝试的是进入我的 gradle 文件（应用程序）并注释掉对该 api 的调用，还将它在应用程序中的每一次出现都从信息更改为按钮。hoang8f.widget.FButton 这样我就可以在没有按钮的情况下工作，并且不会再出现错误。
同时检查您的 styles.xml 文件，如果 "Theme" 有错误，如果有 none，请尝试检查代码。如果您的任何文件抛出任何错误，它应该会告诉您。
如果其他所有方法都失败，请检查此处
如果您使用 android studio v3，您可能需要更改 gradle 版本，您的 gradle 版本也会显示为 3，因此您可以在 [=56] 中降级=]（项目）文件，如：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
