通用的Dialog自定义dialog

图样：

1.自定义dialog的用法

YouMengDialog userMsgDialog=null;

private void initTipDialog() {
userMsgDialog = new YouMengDialog (this);
userMsgDialog.setTitle("系统提示！");
userMsgDialog.setMessage("提示的内容！");
userMsgDialog.setCanceledOnTouchOutside(false);

 userMsgDialog.setButton1("取消", new View.OnClickListener() {
@Override
 public void onClick(View v) {
userMsgDialog.dismiss();

 }
 });

userMsgDialog.setButton2("确定", new View.OnClickListener() {
@Override
 public void onClick(View v) {
userMsgDialog.dismiss();

 }
 });
userMsgDialog.show();
}

2.dialog的java代码

public class YouMengDialog extends Dialog {
private View contentView;
public YouMengDialog(Context context){
super(context, R.style.tran_AlertDialog);
 LayoutInflater inflater = LayoutInflater.from(context);
this.contentView = inflater.inflate(R.layout.dialog, null);
 }
@Override
 protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
 super.onCreate(savedInstanceState);
 setContentView(contentView);
 Window window = this.getWindow();
 WindowManager.LayoutParams lp = window.getAttributes();
 Display d = window.getWindowManager().getDefaultDisplay();
 lp.width = (int) (d.getWidth() * 0.9F);
 window.setAttributes(lp);
 }

//设置提示框标题
public void setTitle(String title){
final TextView textView = (TextView) contentView.findViewById(R.id.title);
 textView.setText(title);
 }
//设置提示的内容
public void setMessage(String message){
final TextView textView = (TextView) contentView.findViewById(R.id.message);
 textView.setText(message);
 }
//对提示框的第一个按键（取消按钮）设置，title：按钮上的文字，onclicklistener ：触发的事件
public void setButton(String title,View.OnClickListener onClickListener){
final Button button = (Button) contentView.findViewById(R.id.dialogButton);
 button.setText(title);
 button.setOnClickListener(onClickListener);
 }

//当只需要一个确定键的时候让取消键隐藏
public void setButtonGone(){
 Button button = (Button) contentView.findViewById(R.id.dialogButton);
 button.setVisibility(View.GONE);

 }

//对提示框的第二个按键（确定按钮）设置，title：按钮上的文字，onclicklistener ：触发的事件

public void setButton2(String title,View.OnClickListener onClickListener){
final Button button = (Button) contentView.findViewById(R.id.dialogButton2);
 button.setText(title);
 button.setOnClickListener(onClickListener);
 }
}

3.用到的样式表

<style name="tran_AlertDialog" parent="@android:style/Theme.Dialog">
 <item name="android:windowFrame">@null</item>
<!-- 边框 -->
 <item name="android:windowIsFloating">true</item>
<!-- 是否浮现在activity之上 -->
 <item name="android:windowIsTranslucent">true</item>
<!-- 半透明 -->
 <item name="android:windowNoTitle">true</item>
<!-- 无标题 -->
 <item name="android:windowBackground">@drawable/gray_corners_border</item>
<!-- 自己想要的背景 -->
 <item name="android:backgroundDimEnabled">true</item>
<!-- 模糊 -->
</style>
