推荐答案

好吧下面是我在实现一个静态类对话框它，所以我可以从任何活动调用它，当我需要的方式

Ok below is my way of implementing dialog its in a static class so I can call it from any activity when I need

public static void showProgressDialog(Context mContext, String text, boolean cancellable)
{
    removeDialog();
    mDialog = new Dialog(mContext, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
    mDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

    LayoutInflater mInflater = LayoutInflater.from(mContext);
    View layout = mInflater.inflate(R.layout.popup_example, null);
    mDialog.setContentView(layout);

    TextView mTextView = (TextView) layout.findViewById(R.id.text);
    if (text.equals(""))
        mTextView.setVisibility(View.GONE);
    else
        mTextView.setText(text);

    mDialog.setOnKeyListener(new DialogInterface.OnKeyListener()
    {
        public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event)
        {
            switch (keyCode)
            {
            case KeyEvent.KEYCODE_BACK:
                return true;
            case KeyEvent.KEYCODE_SEARCH:
                return true;
            }
            return false;

        }
    });

    mDialog.setCancelable(cancellable);

    mDialog.show();
}

public static void removeDialog()
{
    if (mDialog != null)
        mDialog.dismiss();
}
