我想要一个警告对话框弹出后,我点击一个按钮,有一个搜索栏,这样的人可以从1-48更改值。我做了一个自定义XML,有一个搜索栏和两个文本视图和我想的对话框中有两个按钮,一个刚刚取消对话框,另做更多的工作。这里是code我有这么远。
< XML版本=1.0编码=UTF-8&GT?;
< RelativeLayout的

下面是我的警告对话框至今
新AlertDialog.Builder(ImTracking.this)
//是有什么样的setContentView警报对话框?
.setPositiveButton(取消,NULL)
.setNegativeButton(OK,
新DialogInterface.OnClickListener(){
//做一些工作在这里
解决方案
是的 builder.setView(视图V);
这里是如何使用它。
LayoutInflater吹气=(LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
查看布局= inflater.inflate(R.layout.yourLayoutId,(ViewGroup中)findViewById(R.id.yourLayoutRoot));
AlertDialog.Builder建设者=新AlertDialog.Builder(本)
.setView(布局);
AlertDialog alertDialog = builder.create();
alertDialog.show();
搜索栏SB =(搜索栏)layout.findViewById(R.id.yourSeekBar);
sb.setOnSeekBarChangeListener(新SeekBar.OnSeekBarChangeListener(){
公共无效onProgressChanged(搜索栏搜索栏,INT进步,布尔FROMUSER){
//做的东西在这里有新的价值
}
});
编辑:添加progressListener品尝code。做笔记,你不能得到一个引用您的搜索栏,直到的在的调用alertDialog.show(),如果搜索栏不被显示findViewById()将返回null。另请注意,您必须使用 layout.findViewById();
,因为搜索栏是RelativeLayout的一个孩子说'布局'是一个参考。
I want an alert dialog box to pop up after I click a button to have a seek bar so that the person can change the value from 1-48. I've made a custom xml that has a seek bar and two text view and I would like the dialog box to have two buttons, one just cancels the dialog and the other does more work. Here is the code I have so far.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<SeekBar android:max="48" android:layout_height="wrap_content" android:id="@+id/seekBar1" android:layout_width="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_marginTop="74dp"></SeekBar>
<TextView android:text="Change Hour Range" android:layout_height="wrap_content" android:id="@+id/textView1" android:textAppearance="?android:attr/textAppearanceLarge" android:layout_width="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true"></TextView>
<TextView android:text="Only most recent positions" android:layout_height="wrap_content" android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_below="@+id/textView1" android:layout_centerHorizontal="true" android:layout_marginTop="15dp"></TextView>
</RelativeLayout>
Here is the alert dialog that I have so far
new AlertDialog.Builder(ImTracking.this)
//is there something like setcontentview for alert dialogs?
.setPositiveButton("Cancel", null)
.setNegativeButton("OK",
new DialogInterface.OnClickListener() {
// does some work here
解决方案
Yep builder.setView(View v);
here is how you can use it.
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.yourLayoutId, (ViewGroup) findViewById(R.id.yourLayoutRoot));
AlertDialog.Builder builder = new AlertDialog.Builder(this)
.setView(layout);
AlertDialog alertDialog = builder.create();
alertDialog.show();
SeekBar sb = (SeekBar)layout.findViewById(R.id.yourSeekBar);
sb.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser){
//Do something here with new value
}
});
Edit: Added progressListener to sample code. Do note that you cannot get a reference to your SeekBar until after you call alertDialog.show(), if the SeekBar is not being shown findViewById() will return null. Also note that you must use layout.findViewById();
because the SeekBar is a child of the RelativeLayout that 'layout' is a reference to.
