篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了如何启动2活性之间共享单元的过渡?相关的知识,希望对你有一定的参考价值。
我只是了解共享元素在android和我有一个像这ActivitySplashScreen
其中之一,另外一个是为Toolbar
,我想使用共享的元素添加到图像,从ActivitySplashScreen
移动到ActivityMain
经过一番搜索,并试图实现简单的方式让此功能不上我的代码工作,例如:
style.xml:
<style name="AppTheme" parent="BaseTheme">
<item name="android:windowContentTransitions">true</item>
</style>
<style name="BaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
...
</style>
activity splash screen.Java:
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
ButterKnife.bind(this);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent intent = new Intent(ActivitySplashScreen.this, MainActivity.class);
ActivityOptionsCompat options = ActivityOptionsCompat.
makeSceneTransitionAnimation(ActivitySplashScreen.this,
app_logo,
ViewCompat.getTransitionName(app_logo));
startActivity(intent, options.toBundle());
finish();
}
}, 3000);
}
activity main.Java:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
supportPostponeEnterTransition();
}
和我ImageView
和ActivitySplashScreen
XML布局ActivityMain
部件:
<ImageView
android:id="@+id/instagram_add_story"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_marginTop="8dp"
android:layout_marginEnd="16dp"
android:layout_marginBottom="8dp"
android:src="@drawable/img_wizard_1"
android:transitionName="app_logo"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:ignore="VectorDrawableCompat" />
这个代码不工作,以及和我不知道究竟是什么的问题上
更新

答案
我能以这种方式这里使用的是根据你的情况我的解决方案。
样式:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
</resources>

main activity.Java
public class MainActivity extends AppCompatActivity {
@BindView(R.id.toolbar)
Toolbar mToolbar;
Activity mActivity;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
mActivity = this;
setSupportActionBar(mToolbar);
ActivityCompat.postponeEnterTransition(this);
ImageView application_logo = (ImageView) mToolbar.findViewById(R.id.application_logo);
if (getIntent() != null) {
Bundle extras = getIntent().getExtras();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
String imageTransitionName = extras.getString("transition_name");
application_logo.setTransitionName(imageTransitionName);
ActivityCompat.startPostponedEnterTransition(mActivity);
}
}
}
}
这是根据您的情况为SharedElementTransition
的示例代码。每当你使用某种风格总是在样式文件中写,然后使用它。
注:
import android.support.v7.widget.Toolbar;
在Java文件工具栏。这是工作的罚款。
