quickstep/src/com/android/quickstep/views/MeminfoHelper.java
一、首先先对于添加用于内存显示的类方法：
package com.android.quickstep.views;

private static final long PROCESS_REMOVETASKS_DELAY_MS=200L;
private static final String DEFAULT_CONFIG="unconfig";
private static final MainThreadInitializedObject<MeminfoHelper> INSTANCE =
new MainThreadInitializedObject<>(MeminfoHelper::new);
private long mTotalMem=INVALID_MEM_SIZE;
private long mAvailMem=INVALID_MEM_SIZE;
private static final int SI_KUNIT=1000;
private static final int KUINT=1024;
private MeminfoHelper(Context context){
}
public static MeminfoHelper getInstance(final Context context){

}
void showReleaseMemoryToast(Context context,boolean isRemoveView){

}
},PROCESS_REMOVETASKS_DELAY_MS);
}
void updateTotalMemory(){

}
void updateAvailMemory(Context context){

}

}

}
android.util.Log.d(TAG, "getSystemAvailMemory: "+memoryInfo.availMem);

}catch (Exception e){

}
android.util.Log.d(TAG, "getSystemTotalMemory: "+ramSize);
return ramSize;
}
private String getConfig(String key){
return android.os.SystemProperties.get(key,DEFAULT_CONFIG);
}
}
二、在OverviewActionsView方法中添加当最近任务有显示的时候的全部清理及其点击提醒事件：

三、将recentview方法进行公开，在点击全部清除时，可以响应到原有的dismissalltasks方法：
