带EditText的AlertDialog 白色主题 拿来就用

final EditText et = new EditText(this);

new AlertDialog.Builder(this,AlertDialog.THEME_HOLO_LIGHT)
.setTitle("请填写重新预约原因")
//      .setIcon(android.R.drawable.ic_dialog_info)
.setView(et)
.setCancelable(false)
.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
String input = et.getText().toString();
if (input.equals("")) {
Toast.makeText(getApplicationContext(), "重新预约原因不能为空！" + input, Toast.LENGTH_LONG).show();
}
else {
upLoadReason(input);
}
}
})
.setNegativeButton("取消", null)
.show();
