Android的，搜索栏对话框 [英] Android, SeekBar in dialog

问题描述

我想用一个对话框，在我的应用程序中的搜索栏。 但我真的不知道该怎么办becouse我没有与Android体验。

I would like to use a dialog with a seekbar in my application. But i dont really know how to do becouse i lack experience with android.

所以，当你preSS按钮：一个对话框应出现，有一个搜索栏，用户可以输入一个值，然后preSS OK按钮

So, when you press a button: a dialog should come up, with a seekbar and the user is able to enter a value and then press OK-button.

在codeI目前所面对的是默认的code。通过developer.android

The code i have at the moment is the default code by developer.android

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure you want to exit?")
        .setCancelable(false)
       .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                MyActivity.this.finish();
       }
   })
   .setNegativeButton("No", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
       }
   });
AlertDialog alert = builder.create();

我应该怎么做才能增加一个搜索栏？

How should I do to add a SeekBar?

谢谢！

推荐答案

也许你会认为创建一个自定义对话框;它需要更多的工作，但它通常对我的作品;） 为你的对话框创建一个新的布局文件（比如说，your_dialog.xml）：

Maybe you could think of create a custom dialog; it requires more work but it usually works for me ;) Create a new layout file for your dialog (say, your_dialog.xml):

<RelativeLayout
android:id="@+id/your_dialog_root_element"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>

<SeekBar
    android:id="@+id/your_dialog_seekbar"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    >
</SeekBar>

<Button
    android:id="@+id/your_dialog_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
</Button>

然后，在你的活动：

Dialog yourDialog = new Dialog(this);
LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.your_dialog, (ViewGroup)findViewById(R.id.your_dialog_root_element));
yourDialog.setContentView(layout);

因此​​，您可以在元素上进行如下操作：

Thus, you can operate on your element as follows:

Button yourDialogButton = (Button)layout.findViewById(R.id.your_dialog_button);
SeekBar yourDialogSeekBar = (SeekBar)layout.findViewById(R.id.your_dialog_seekbar);
// ...

等，设置监听按钮和搜索栏。

and so on, to set listeners for button and seekbar.

编辑： onchangelistener应为搜索栏如下：

The seekbar onchangelistener should be as follows:

OnSeekBarChangeListener yourSeekBarListener = new OnSeekBarChangeListener() {
    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {
            //add code here
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {
            //add code here
    }

    @Override
    public void onProgressChanged(SeekBar seekBark, int progress, boolean fromUser) {
            //add code here
    }
 };
 yourDialogSeekBar.setOnSeekBarChangeListener(yourSeekBarListener);
