android应用的loading加载动画制作(启动跳转画面)

加载界面只需要一张logo，颜色渐深，三秒显示后跳入下一个activity，同时去掉标题栏与状态栏。代码如下：AppLoadingActivity.java中

public class AppLoadingActivity extends Activity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

// 取消标题栏(也可以在manifest里面配置)

// this.requestWindowFeature(Window.FEATURE_NO_TITLE);

// 取消状态栏

this.getWindow().setFlags(youtParams.FLAG_FULLS CREEN,

youtParams.FLAG_FULLSCREEN);

setContentView(yout.app_loading);

// 三秒钟之后进入login

ImageView loadingIv = (ImageView) this.findViewById(R.id.logo_bg);

// 从浅到深,从百分之10到百分之百

AlphaAnimation animation = new AlphaAnimation(0.1f, 1.0f);

animation.setDuration(3000);

loadingIv.setAnimation(animation);

// 给animation设置监听器

animation.setAnimationListener(new AnimationListener() {

@Override

public void onAnimationStart(Animation animation) {

// TODO Auto-generated method stub

}

@Override

public void onAnimationRepeat(Animation animation) {

// TODO Auto-generated method stub

}

@Override

public void onAnimationEnd(Animation animation) {

// TODO Auto-generated method stub

// 三秒之后跳出

Intent it = new Intent(AppLoadingActivity.this, MainActivity.class);

startActivity(it);

// 三秒之后这个窗口就没用了应该finish

finish();

}

});

}

}

app_loading.xml:

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

android:id="@+id/logo_bg"

android:background="@drawable/app_loading"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

/>

AppLoadingManifest.xml:

package="com.android.aming.apploading"

android:versionCode="1"

android:versionName="1.0">

android:label="@string/app_name"

//这个属性可以消除加载应用中间的黑屏

android:theme="@android:style/Theme.Translucent">

android:label="@string/app_name">
