我怎样才能打开动画编程？ [英] How can I turn on animation programatically?

问题描述

我怎样才能打开动画编程？我使用 overridePendingTransition（）; 。它不工作，除非我自己打开的动画。谁能告诉我怎么打开动画编程这是内部的显示/动画设置？我使用overridePendingTransition（）;打开新的活动。

下面是我的XML

grow_fadein_center

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;＆LT;设置的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android＆GT;
    ＆LT;规模以上的android：fromXScale =0.6机器人：toXScale =1.0
           机器人：fromYScale =0.6机器人：toYScale =1.0
           机器人：pivotX =50％的android：pivotY =50％
           机器人：时间=@安卓整数/ config_longAnimTime/＆GT;
    ＆LT;阿尔法机器人：插值=@动画/ decelerate_interpolator
            机器人：fromAlpha =0.0机器人：toAlpha =1.0
            机器人：时间=@安卓整数/ config_longAnimTime/＆GT;
＆LT; /集＆gt;
 

shrink_fadeout_center：

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT;设置的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android＆GT;
    ＆LT;规模以上的android：fromXScale =1.0机器人：toXScale =0.5
           机器人：fromYScale =1.0机器人：toYScale =0.5
           机器人：pivotX =50％的android：pivotY =50％
           机器人：时间=@安卓整数/ config_longAnimTime/＆GT;
    ＆LT;阿尔法机器人：插值=@动画/ accelerate_interpolator
            机器人：fromAlpha =1.0机器人：toAlpha =0.0
            机器人：时间=@安卓整数/ config_longAnimTime/＆GT;
＆LT; /集＆gt;
 

和这里是code我使用打开的意图

  btn.setOnClickListener（新OnClickListener（）{            @覆盖
            公共无效的onClick（视图v）{
                // TODO自动生成方法存根                ContentResolver的CR = getContentResolver（）;
                Settings.System.putInt（CR，Settings.System.WINDOW_ANIMATION_SCALE，0）;                意向意图=新意图（背景下，Second.class）;
                startActivity（意向）;
                overridePendingTransition（R.anim.grow_fade_in_center，R.anim.shrink_fade_out_center）;
                完（）;//在TextView的测试工作没有开启系统的动画。
                动画动画= AnimationUtils.loadAnimation（背景下，R.anim.grow_fade_in_center）;
                txt.startAnimation（动画）;
            }
        }）;
 

这只有在动画开启工作。而我通过设置 - >显示 - >动画

我发现

  ContentResolver的CR = getContentResolver（）;
Settings.System.putInt（CR，Settings.System.WINDOW_ANIMATION_SCALE，0）;
 

要打开或关闭动画通过设置整数！但它并没有对我的工作！
我需要的是我怎么能打开/关闭动画编程这是在系统设置？

解决方案

您不需要务实启动动画类的。

您只需要调用 overridePendingTransition（R.anim.grow_fade_in_center，R.anim.shrink_fade_out_center）; 在正确的位置。

 公共无效的onClick（视图v）{
    startActivity（HomeActivity.class）;
    overridePendingTransition（android.R.anim.fade_in，android.R.anim.fade_out）;
    完（）;
}
 

也做的：

  Settings.System.putInt（CR，Settings.System.WINDOW_ANIMATION_SCALE，0）;
 

请问禁用窗口动画！

How can I turn on animation programatically? I am using overridePendingTransition();. It doesn't work unless I turn on animation myself. Can anybody tell me how to turn on animations programatically which are inside display/Animation setting? I am using overridePendingTransition(); to open new activity .

here are my xml

grow_fadein_center

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale android:fromXScale="0.6" android:toXScale="1.0"
           android:fromYScale="0.6" android:toYScale="1.0"
           android:pivotX="50%" android:pivotY="50%"
           android:duration="@android:integer/config_longAnimTime" />
    <alpha android:interpolator="@anim/decelerate_interpolator"
            android:fromAlpha="0.0" android:toAlpha="1.0"
            android:duration="@android:integer/config_longAnimTime" />
</set>

shrink_fadeout_center :

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale android:fromXScale="1.0" android:toXScale="0.5"
           android:fromYScale="1.0" android:toYScale="0.5"
           android:pivotX="50%" android:pivotY="50%"
           android:duration="@android:integer/config_longAnimTime" />
    <alpha android:interpolator="@anim/accelerate_interpolator"
            android:fromAlpha="1.0" android:toAlpha="0.0"
            android:duration="@android:integer/config_longAnimTime"/>
</set>

and here is the code i am using to open intent

btn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                ContentResolver cr = getContentResolver();
                Settings.System.putInt(cr, Settings.System.WINDOW_ANIMATION_SCALE, 0);

                Intent intent=new Intent(context,Second.class);


                startActivity(intent);
                overridePendingTransition(R.anim.grow_fade_in_center, R.anim.shrink_fade_out_center);
                finish();

//testing on textview worked without turning system animation on.
                Animation animation=AnimationUtils.loadAnimation(context, R.anim.grow_fade_in_center);
                txt.startAnimation(animation);




            }
        });

This works only when animations are turned on. and i am doing so by settings->display->animation

I found

ContentResolver cr = getContentResolver();
Settings.System.putInt(cr, Settings.System.WINDOW_ANIMATION_SCALE, 0);

to turn on or off animation by setting integer! but it didn't work for me! what i need is how can i turned on/off animation programatically which are in system setting?

解决方案

You do not need to initiate the Animation pragmatically like that.

You just need to call overridePendingTransition(R.anim.grow_fade_in_center, R.anim.shrink_fade_out_center); in the correct place.

public void onClick(View v) {
    startActivity(HomeActivity.class);
    overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
    finish();
}

Also doing:

Settings.System.putInt(cr, Settings.System.WINDOW_ANIMATION_SCALE, 0);

Will disabled window animations!
