部分显示AlertDialog中的按钮

Question

我已经使用OK按钮创建了一个AlertDialog。但它只是部分显示按钮。

screenshot

我使用以下代码

private void showErrorDialog(String msg) {
            final int 
    //Log.i(tag, "showAlert with message: " + msg);
    final AlertDialog.Builder errDialog = new AlertDialog.Builder(context);

    errDialog.setCancelable(false).setPositiveButton("Ok", listener);

    TextView txtView = new TextView(context);
    txtView.setSingleLine(false);
    txtView.setText(msg);

    errDialog.setView(txtView);

    //Log.i(tag, "dialog created");
    context.runOnUiThread(new Runnable() {

        @Override
        public void run() {
            //Log.i(tag, "showing dialog ..............");
            MyUIClass.errorDialog = errDialog.create();
            context.showDialog(MyUIClass.ERROR_DIALOG_ID/* , null */);
        }
    });
    //Log.i(tag, "show()");
}

可能是什么问题？

在你的函数中使用下面的代码::

AlertDialog.Builder alert = new AlertDialog.Builder(context);
        alert.setTitle(null);
        alert.setCancelable(false);
        alert.setMessage(msg);
        alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub
                //Do nothing
            }
        });
        alert.show();

您尚未声明对话框的大小，请检查此

 private void showErrorDialog(String msg) {
               // final int 
        //Log.i(tag, "showAlert with message: " + msg);
        final AlertDialog.Builder errDialog = new AlertDialog.Builder(context);
       // errDialog.setLayoutParams(new LayoutParams(500,LayoutParams.WRAP_CONTENT); 
        errDialog.setCancelable(false).setPositiveButton("Ok", listener);


        TextView txtView = new TextView(context);
        txtView.setSingleLine(false);
        txtView.setText(msg);
       errDialog.addView(txtView , new LayoutParams(MATCH_PARENT, WRAP_CONTENT));

       //errDialog.setView(txtView);

        //Log.i(tag, "dialog created");
        context.runOnUiThread(new Runnable() {

        @Override
        public void run() {
            //Log.i(tag, "showing dialog ..............");
            MyUIClass.errorDialog = errDialog.create();
            context.showDialog(MyUIClass.ERROR_DIALOG_ID/* , null */);
        }
    });
    //Log.i(tag, "show()");

}

如果希望自定义视图在其下方显示TextView和按钮，则必须使用对话框。
