Question

我是android studio的新手

我正在努力建立这个项目

https://github.com/CodingInfinite/AndroidLoginScreen

我遇到了很多我已修复的错误，但该应用仍然无法运行

打开并崩溃

这是错误

Answer 1

首先，请确保您具有TextInputEditText的依赖项。将此添加到依赖项下的build.gradle（app）中：

implementation 'com.android.support:design:28.0.0'

接下来，将您的AppCompatActivity导入更改为：

import android.support.v7.app.AppCompatActivity;

最后，将以下内容添加到initViews方法中的所有视图中。将this一词放在所有findViewById()调用之前。它们应如下所示：

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);
}

希望这对您有用！这使它在我的头上运行。

更新：

这是我能够运行的应用程序中的build.gradle（app）。

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 23
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:design:28.0.0'
}

Answer 2

You got error with android.support.design.widget.TextInputEditText at 
       android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2416)

我认为您的设计库存在问题。迁移到androidx并使用此库：

实现'com.google.android.material：material：1.0.0'

尝试将主题更改为：

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">

Answer 3

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
        public void onFinish() {
            bookIconImageView.setImageResource(R.drawable.background_color_book);
            rootView.setBackgroundColor(ContextCompat.getColor(MainActivity.this, R.color.colorSplashText));
            loadingProgressBar.setVisibility(GONE);
            startAnimation();

        }
    }.start();
