View view = View.inflate(this, R.layout.layout_dialog, null);
        AlertDialog alertDialog = new AlertDialog.Builder(TabActivity.this, R.style.CustomDialog).create();
        alertDialog.setContentView(view);
        alertDialog.show();
        alertDialog.setCanceledOnTouchOutside(true);
        alertDialog.setCancelable(true);

运行上面的代码报错：

原因：

于dialog.show()之前调用了dialog.setContentView()或者dialog.getwindow()等，正确的应该是dialog.show()之后调用dialog.setContentView()
