android BottomSheetDialog优雅实现分享菜单

BottomSheetDialog是23.2中加的一个新的控件,继承AppCompatDialog类
官方描述Base class for Dialogs styled as a bottom sheet.
使用起来 很简单,

 BottomSheetDialog dialog = new BottomSheetDialog(this);
 dialog.setContentView(view);
dialog.show();

创建一个BottomSheetDialog 然后setContentView,剩下的就是对view进行操作
我们就是实现一个分享菜单先上效果图

实现

   BottomSheetDialog dialog = new BottomSheetDialog(MainActivity.this);
                View view = View.inflate(MainActivity.this, R.layout.bottom_dialog, null);
                dialog.setContentView(view);
                recyclerView = (RecyclerView) dialog.findViewById(R.id.recycler);
                recyclerView.setLayoutManager(new GridLayoutManager(MainActivity.this, 3));
                recyclerView.setHasFixedSize(true);
                recyclerView.setAdapter(new Adapter());
                dialog.show();

adapter

 public class Adapter extends RecyclerView.Adapter {
        Adapter() {
            list = getShareAppList();
            if (list == null) {
                return;
            }
        }

        @Override
        public ViewHolde onCreateViewHolder(ViewGroup parent, int viewType) {
            return new ViewHolde(getLayoutInflater().inflate(R.layout.recycler_item, null));
        }

        @Override
        public void onBindViewHolder(ViewHolde holder, final int position) {
            holder.appTextView.setText(list.get(position).appName);
            holder.iconImageView.setImageDrawable(list.get(position).icon);
            holder.itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    Intent shareIntent = new Intent(Intent.ACTION_SEND);
                    AppBean appBean = list.get(position);
                    shareIntent.setComponent(new ComponentName(appBean.pkgName, appBean.appLauncherClassName));
                    shareIntent.setType("text/plain");
                    shareIntent.putExtra(Intent.EXTRA_TEXT, "分享内容");
                    shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    startActivity(shareIntent);
                }
            });
        }

        @Override
        public int getItemCount() {
            return list == null ? 0 : list.size();
        }
    }

获取应用分享代码

 public List getShareApps(Context context) {
        List mApps = new ArrayList();
        Intent intent = new Intent(Intent.ACTION_SEND, null);
        intent.addCategory(Intent.CATEGORY_DEFAULT);
        intent.setType("text/plain");
//      intent.setType("*/*");
        PackageManager pManager = context.getPackageManager();
        mApps = pManager.queryIntentActivities(intent,
                PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);
        return mApps;
    }

    private List getShareAppList() {
        List shareAppInfos = new ArrayList();
        PackageManager packageManager = getPackageManager();
        List resolveInfos = getShareApps(MainActivity.this);
        if (null == resolveInfos) {
            return null;
        } else {
            for (ResolveInfo resolveInfo : resolveInfos) {
                AppBean appBean = new AppBean();
                appBean.pkgName = (resolveInfo.activityInfo.packageName);
//              showLog_I(TAG, "pkg>" + resolveInfo.activityInfo.packageName + ";name>" + resolveInfo.activityInfo.name);
                appBean.appLauncherClassName = (resolveInfo.activityInfo.name);
                appBean.appName = (resolveInfo.loadLabel(packageManager).toString());
                appBean.icon = (resolveInfo.loadIcon(packageManager));
                shareAppInfos.add(appBean);
            }
        }
        return shareAppInfos;
    }

xml和AppBean 就不放了
