Question

我使用以下代码显示单击TextView时的进度对话框：

 contacts.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog = new ProgressDialog(GroupChatActivity.this);
            dialog.setMessage("Loading Contacts...");
            dialog.show();
            Toast.makeText(getApplicationContext(), "Contacts Clicked", Toast.LENGTH_SHORT).show();
            popupWindow.dismiss();
            ArrayList<Bean_PhoneNumbers> listBeanPhone = getContactsFromPhone();
            Intent intent = new Intent(GroupChatActivity.this, PhoneBookActivity.class);
            //intent.putExtra("listBeanPhone", listBeanPhone);
            intent.putParcelableArrayListExtra("listBeanPhone", listBeanPhone);
            intent.putExtra("GroupRoomID", roomID);
            Log.e("rID", roomID);
            startActivity(intent);
        }
    });

当活动被销毁时，ProgressDialog被解雇。

 protected void onDestroy() {
    super.onDestroy();
    dialog.dismiss();
}

但点击联系人时，“进度”对话框不会立即显示，需要花费太多时间。请帮我解决问题。

尝试这样。在Listener

之外初始化对话框

        dialog = new ProgressDialog(GroupChatActivity.this);
        dialog.setMessage("Loading Contacts...");
        ArrayList<Bean_PhoneNumbers> listBeanPhone = getContactsFromPhone();

    contacts.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        dialog.show();
        Toast.makeText(getApplicationContext(), "Contacts Clicked", Toast.LENGTH_SHORT).show();
        popupWindow.dismiss();

        Intent intent = new Intent(GroupChatActivity.this, PhoneBookActivity.class);
        //intent.putExtra("listBeanPhone", listBeanPhone);
        intent.putParcelableArrayListExtra("listBeanPhone", listBeanPhone);
        intent.putExtra("GroupRoomID", roomID);
        Log.e("rID", roomID);
        startActivity(intent);
    }
});

单击TextView后，ProgessDialog不会立即显示
