Android开发实现一个沙漠风情动画效果

Android开发实现一个沙漠风情动画效果

将其添加到存储库末尾的根build.gradle中：

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

添加依赖项

dependencies {
    compile 'com.github.jetradarmobile.desertplaceholder:desertplaceholder:1.2.4'
}

用法

将视图添加到您的布局

  <com.jetradar.desertplaceholder.DesertPlaceholder
      android:id="@+id/placeholder"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      app:dp_buttonText="retry"
      app:dp_message="Use this nice placeholder if you have nothing to show"/>
Set up listener to button click

   DesertPlaceholder desertPlaceholder = (DesertPlaceholder) findViewById(R.id.placeholder);
    desertPlaceholder.setOnButtonClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        // do stuff
      }
    });
Testing

  @Rule
  public final ActivityTestRule<MainActivity> activityRule  = new ActivityTestRule<MainActivity>(MainActivity.class) {
    @Override
    protected void beforeActivityLaunched() {
      //...
      DesertPlaceholder.animationEnabled = false;
    }
  };

  @Test
  public void placeholder() {
    onView(withId(R.id.placeholder))
        .perform(click()) // will freeze here if animation enabled
        .check(matches(isDisplayed()));
  }
