Question

如何在使用ACTION_SEND意图时过滤掉特定应用？这个问题已经以各种方式提出，但我还没有能够根据给出的答案收集解决方案。希望有人可以提供帮助。我想提供在应用程序内共享的功能。喜欢这张照片！ http://i.imgur.com/6yeUfgV.png

由于您无法控制可用的应用程序，您需要自己对该对话框进行硬编码，然后根据用户的选择，专门启动ACTION_SEND意图。

本网站的解释：http://clickclickclack.wordpress.com/2012/01/03/intercepting-androids-action_send-intents/

创建一个活动“ShareActivity”，显示带有ListView的布局。然后按以下方式实现适配器：

public class ShareIntentListAdapter extends ArrayAdapter
{
    Activity context;
    Object[] items;
    boolean[] arrows;
    int layoutId;

    public ShareIntentListAdapter(Activity context, int layoutId, Object[] items) {
        super(context, layoutId, items);

        this.context = context;
        this.items = items;
        this.layoutId = layoutId;
    }

    public View getView(int pos, View convertView, ViewGroup parent) {
        LayoutInflater inflater=context.getLayoutInflater();
        View row = inflater.inflate(layoutId, null);
        TextView label = (TextView) row.findViewById(R.id.text1);
        label.setText(((ResolveInfo)items[pos]).activityInfo.applicationInfo.loadLabel(context.getPackageManager()).toString());
        ImageView image = (ImageView) row.findViewById(R.id.logo);
        image.setImageDrawable(((ResolveInfo)items[pos]).activityInfo.applicationInfo.loadIcon(context.getPackageManager()));

        return(row);
    }
}

然后在你的“ShareActivity”中，给listView充气，创建一个数组，其中包含你想要为你想要的每个意图显示的内容（例如logo / name / FB，FB Messenger，Twitter等等），以及然后使用此数组创建ShareIntentListAdapter并将其附加到listView。

最后一步是处理onClick方法，点击项目并启动所选的意图。

作为@NSimon回答我是通过自己硬编辑这个对话框得到的，然后根据用户的选择，专门启动ACTION_SEND意图

public void ShareDialog_popualate() {
    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    builder.setTitle(getResources().getString(R.string.sharingBy));
    ListView list = new ListView(MainActivity.this);
    list.setBackgroundColor(getResources().getColor(R.color.white));
    list.setAdapter(new SharingListAdapter(MainActivity.this));
    list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1,
                int position, long arg3) {
            // TODO Auto-generated method stub
            if (sharedialog.isShowing()) {
                sharedialog.dismiss();
            }
            IntentShareApp(position);
//              Toast.makeText(MainActivity.this,
//                      "Clicked at Position" + position, Toast.LENGTH_SHORT)
 //                     .show();
        }
    });
    builder.setView(list);
    sharedialog = builder.create();
    sharedialog.show();
}

和listadapter的cumstome类是

 package com.artgine.daleel;

 import android.content.Context;
 import android.view.LayoutInflater;
 import android.view.View;
 import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ListAdapter;
 import android.widget.TextView;

public class SharingListAdapter extends BaseAdapter implements ListAdapter {

private Context mContext;
private LayoutInflater inflator;
String[]sharing_names={"Facebook","Whatsapp","Messenger"};
final int[] images = { R.drawable.share_icon,
        R.drawable.ic_launcher, R.drawable.send_msg_icon_cancel,
         };
public SharingListAdapter(Context context) {
    // TODO Auto-generated constructor stub
this.mContext=context;
this.inflator= (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return images.length;
}

@Override
public Object getItem(int arg0) {
    // TODO Auto-generated method stub
     return arg0;
}

@Override
public long getItemId(int arg0) {
    // TODO Auto-generated method stub
    return arg0;
}

@Override
public View getView(int position, View convertView, ViewGroup arg2) {
    // TODO Auto-generated method stub
    MainListHolder mHolder;

    View v = convertView;
    if (convertView == null)
    {
        mHolder = new MainListHolder();

        v = inflator.inflate(R.layout.share_items, null);
        mHolder.image=  (ImageView) v.findViewById(R.id.imgviewshareicon);
        mHolder.text=(TextView)v.findViewById(R.id.sharenamebtn); 
        v.setTag(mHolder);
    } else {
        mHolder = (MainListHolder) v.getTag();
    }

    mHolder.image.setImageResource(images[position]);
    mHolder.image.setPadding(20, 20, 20, 20);
    mHolder.text.setText(sharing_names[position]);
    return v;
}
class MainListHolder
{
    private ImageView image;
    private TextView text;
}
}

以及作为用户选择的内容actionsend

 public void IntentShareApp(int position) {
    String palystoreApplink = "http://play.google.com/store/apps/details?id="
            + this.getPackageName();        
    Intent intent = new Intent(
            android.content.Intent.ACTION_SEND);
    intent.setType("text/plain");
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);

    // Add data to the intent, the receiving app will
    // decide
    // what to do with it.
    intent.putExtra(Intent.EXTRA_TEXT,palystoreApplink);
    intent.putExtra(Intent.EXTRA_SUBJECT,getResources().getString(R.string.app_name));
    startActivity(Intent.createChooser(intent,getResources().getString(R.string.sharingBy)));

}
