启动特殊的应用程序，防止意图选择器

我已经声明了自定义操作，Intent并基于可以处理该问题的应用程序构建了UI Intent。既然我知道按钮单击应该启动哪个应用程序，如何防止选择器显示所有可能的应用程序。

final Intent intent = new Intent();
intent.setAction(CUSTOM_ACTION);

PackageManager packageManager = getPackageManager();
final List<ResolveInfo> activities = packageManager
        .queryIntentActivities(intent, 0);

for (int i = 0; i < activities.size(); i++) {
    final ResolveInfo info = activities.get(i);

    Button b = new Button(this);
    b.setText(info.loadLabel(packageManager));

    b.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // This line was the solution
            intent.setPackage(info.activityInfo.packageName);

            startActivityForResult(intent, REQUEST_CODE);
        }
    });

    mLayout.addView(b);
}

谢谢。
