尝试构建 github 项目时出错
Getting errors trying to build a github project
我是 android 工作室的新人
我正在努力构建这个项目

我修复了很多错误，但该应用仍然无法正常运行 运行
它打开并崩溃

首先，确保您具有 TextInputEditText 的依赖项。将此添加到依赖项下的 build.gradle(app)：
implementation 'com.android.support:design:28.0.0'
接下来，将 AppCompatActivity 的导入更改为：
import android.support.v7.app.AppCompatActivity;
最后，将以下内容添加到 initViews 方法中的所有视图。将单词 this 放在所有 findViewById() 调用的前面。它们应该如下所示：
private void initViews() {
bookIconImageView = this.findViewById(R.id.bookIconImageView);
bookITextView = this.findViewById(R.id.bookITextView);
loadingProgressBar = this.findViewById(R.id.loadingProgressBar);
rootView = this.findViewById(R.id.rootView);
afterAnimationView = this.findViewById(R.id.afterAnimationView);
}
希望这对你有用！这在我这边得到了 运行。
更新：
这是我能够从我的应用程序中获得的 build.gradle(app) 运行。

bookITextView.setVisibility(GONE);

首先，确保您具有 TextInputEditText 的依赖项。将此添加到依赖项下的 build.gradle(app)：
implementation 'com.android.support:design:28.0.0'
接下来，将 AppCompatActivity 的导入更改为：
import android.support.v7.app.AppCompatActivity;
最后，将以下内容添加到 initViews 方法中的所有视图。将单词 this 放在所有 findViewById() 调用的前面。它们应该如下所示：
private void initViews() {
bookIconImageView = this.findViewById(R.id.bookIconImageView);
bookITextView = this.findViewById(R.id.bookITextView);
loadingProgressBar = this.findViewById(R.id.loadingProgressBar);
rootView = this.findViewById(R.id.rootView);
afterAnimationView = this.findViewById(R.id.afterAnimationView);
}
希望这对你有用！这在我这边得到了 运行。
更新：
这是我能够从我的应用程序中获得的 build.gradle(app) 运行。

将 CountDownTimer 更改为
new CountDownTimer(5000, 1000) {
@Override
public void onTick(long millisUntilFinished) {
bookITextView.setVisibility(GONE);
loadingProgressBar.setVisibility(VISIBLE);
bookIconImageView.setImageResource(R.drawable.white_book_icon);
rootView.setBackgroundColor(ContextCompat.getColor(MainActivity.this, R.color.colorBackground));
}
@Override

rootView.setBackgroundColor(ContextCompat.getColor(MainActivity.this, R.color.colorSplashText));
loadingProgressBar.setVisibility(GONE);
startAnimation();
