launcher中隐藏应用图标

隐藏指定应用图标

1、com/android/launcher3/AppFilter.java

package com.android.launcher3;

import android.content.ComponentName;
import android.content.Context;
import com.android.launcher3.util.ResourceBasedOverride;

public class AppFilter implements ResourceBasedOverride {
    
    
    //这里可以看出反射app_filter_class字符串的配置初始化具体的类
    //我们就可以写一个类继承AppFilter,重写shouldShowApp方法 实现屏蔽
    public static AppFilter newInstance(Context context) {
    
    
        return Overrides.getObject(AppFilter.class, context, R.string.app_filter_class);
    }
    public boolean shouldShowApp(ComponentName app) {
    
    
        return true;
    }
}

2、res配置

<string name="app_filter_class" translatable="false">com.android.launcher3.CustomAppFilter</string>

3、com/android/launcher3/CustomAppFilter.java

package com.android.launcher3;
import android.content.ComponentName;
import android.content.Context;
import java.util.Arrays;

public class CustomAppFilter extends AppFilter {
    
    
   private String[]  HIDE_PACKAGE = {
    
    "com.google.android.documentsui","cn.com.blacksesame.stereocalib2","com.android.documentsui"};
    public CustomAppFilter(Context context) {
    
    
    }
    @Override
    public boolean shouldShowApp(ComponentName app) {
    
    
      if(Arrays.asList(HIDE_PACKAGE).contains(app.getPackageName())) {
    
    
         return false;
      } else {
    
    
         return true;
      }
    }
}

4、以上只屏蔽了应用图标加载流程
如果有些应用是连外网登陆Google Play之后, 由三方apk发送广播添加到桌面多出来的图标,需要另外过滤
