text 文本样式粗斜体以及在listView中使用超链接

// Get our EditText object.
EditText vw = (EditText)findViewById(R.id.text);

// Set the EditText's text.
vw.setText("Italic, highlighted, bold.");

// If this were just a TextView, we could do:
// vw.setText("Italic, highlighted, bold.", TextView.BufferType.SPANNABLE);
// to force it to use Spannable storage so styles can be attached.
// Or we could specify that in the XML.

// Get the EditText's internal text storage
Spannable str = vw.getText();

// Create our span sections, and assign a format to each.
str.setSpan(new StyleSpan(android.graphics.Typeface.ITALIC), 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
str.setSpan(new BackgroundColorSpan(0xFFFFFF00), 8, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
str.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 21, str.length() - 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

或者

mBox = new TextView(context); mBox.setText(Html.fromHtml("<b>" + title + "</b>" +  "<br />" +                         "<small>" + description + "</small>" + "<br />" +                         "<small>" + DateAdded + "</small>");

想在listView中使用超链接 可以继承custom adapter并在getView

textcontent.setText(Html.fromHtml(item.get_text()));
textcontent.setAutoLinkMask(Linkify.WEB_URLS);
然后在

<TextView
                android:id="@+id/txtview"
                android:autoLink="web"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:text="put your link here"/>

 下标：

mtTextView.setText(Html.fromHtml("HC0₃"));

SlidingDrawer的使用
1.更换hendler
mSlidingDrawer.setOnDrawerScrollListener(new OnDrawerScrollListener(){
                 @Override
                public void onScrollEnded() {
                 // TODO Auto-generated method stub
                      Log.i("ddd","onScrollEnded slider");
                     
                       slider_animation.reverseTransition(HANDLE_ANIMATION_SPEED);
                             }
                 @Override
                
                 public void onScrollStarted() {
                  // TODO Auto-generated method stub                                          
                    Log.i("ddd","onScrollStarted slider"); 
                     slider_animation.startTransition(HANDLE_ANIMATION_SPEED);
                                                          }});

要在上面的函数执行 不能
ImageView handle = (ImageView)findViewById(R.id.handle_l);
     handle.setFocusable(true);
     handle.setOnClickListener(new OnClickListener(){
    
                     @Override
                    public void onClick(View v) {
                   
                        // TODO Auto-generated method stub
                    Log.i("test","onClick");                }    });

阻止EditText 开始就获得焦点

在listView中或其他格式中存在editView，尤其是listView和editView并存的时候 程序运行veditvview 就获得焦点，如何让他不获得焦点呢

EditText.setSelected(false);

上述命令是不行的。

clearFocus() 才是可以的。

 

如果你是用AutoCompleteTextView

<!-- Dummy item to prevent AutoCompleteTextView from receiving focus -->
<LinearLayout
    android:focusable="true" android:focusableInTouchMode="true"
    android:layout_width="0px" android:layout_height="0px"/>

<!-- :nextFocusUp and :nextFocusLeft have been set to the id of this component
     to prevent the dummy from receiving focus again -->
<AutoCompleteTextView android:id="@+id/text"
        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:nextFocusUp="@+id/text" android:nextFocusLeft="@+id/text"/>
