android 应用的loading加载动画制作(闪屏)

androidanimationlayoutencodingapplicationaction

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(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.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:

    <application android:icon="@drawable/icon" android:label="@string/app_name"

//这个属性可以消除加载应用中间的黑屏
