所以我試圖在動畫中實現啓動畫面和圖像視圖淡入淡出,我想要同時啓動啓動畫面活動。我還希望啓動屏幕活動在短暫延遲後結束(觸摸事件是可選的),在圖像視圖動畫完成後。在ImageView動畫中淡入淡出的畫面
我SplashScreen.java:
package hillbillys.delivery;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
import android.widget.Toast;
public class SplashScreen extends AppCompatActivity implements Animation.AnimationListener {
protected Animation fadeIn;
protected ImageView img1;
protected ImageView img2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.screen_splash);
fadeIn = AnimationUtils.loadAnimation(this,R.anim.fade_in);
/*
img1.setVisibility(View.VISIBLE);
img2.setVisibility(View.VISIBLE);
img1.startAnimation(fadeIn);
img2.startAnimation(fadeIn);
*/
Thread timerThread = new Thread(){
public void run(){
try{
sleep (2000);
}catch(InterruptedException e){
e.printStackTrace();
}finally{
Intent intent = new Intent(SplashScreen.this,MainActivity.class);
startActivity(intent);
}
}
};
timerThread.start();
}
@Override
protected void onPause() {
super.onPause();
finish();
}
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
Toast.makeText(getBaseContext(), "Animation Stopped!", Toast.LENGTH_SHORT).show();
}
@Override
public void onAnimationRepeat(Animation animation) {
}
}
應用程序崩潰每次我嘗試添加的代碼塊在留言的時候,無論在什麼地方,我把它。沒有淡入淡出動畫工作就好了。有什麼辦法可以輕鬆地同步這兩個?在編碼方面我相當新,所以在我試圖實現的東西中可能會有一些致命的錯誤。
我screeen_splash.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fff0d9"
android:orientation="vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageView"
android:layout_gravity="center_horizontal"
android:src="@drawable/logo1"
android:layout_marginTop="250dp"
android:visibility="gone" />
<ImageView
android:layout_width="260dp"
android:layout_height="41dp"
android:id="@+id/imageView2"
android:layout_gravity="center_horizontal"
android:src="@drawable/logo2"
android:visibility="gone" />
</LinearLayout>
我fade_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<alpha
android:duration="1000"
android:fromAlpha="0.0"
android:interpolator="@android:anim/accelerate_interpolator"
android:toAlpha="1.0"
/>
</set>
您可以使用Picasso加載ImageView和淡入淡出動畫。睡眠後(2000)再次使用畢加索。 – PatrickMA
