Android clickable TextView with hint and image to start search dialog and present selected result
I'm searching for an example that shows how I can implement a clickable textview that starts the Android default search dialog and displays a selected result line.
It should have the same behaviour and design as the search field in the Google Maps action bar on Android (e. g. magnifier glass icon on the left, a "Search" hint if the textview is empty, a click starts the search dialog defined by a searchab开发者_运维百科le entry):
That is custom EditText
with compound drawable
public class SearchEditText extends EditText {
private boolean mMagnifyingGlassShown = true;
private Drawable mMagnifyingGlass;
public SearchEditText(Context context, AttributeSet attrs) {
super(context, attrs);
mMagnifyingGlass = getCompoundDrawables()[0];
}
/**
* Conditionally shows a magnifying glass icon on the left side of the text field
* when the text it empty.
*/
@Override
public boolean onPreDraw() {
boolean emptyText = TextUtils.isEmpty(getText());
if (mMagnifyingGlassShown != emptyText) {
mMagnifyingGlassShown = emptyText;
if (mMagnifyingGlassShown) {
setCompoundDrawables(mMagnifyingGlass, null, null, null);
} else {
setCompoundDrawables(null, null, null, null);
}
return false;
}
return super.onPreDraw();
}
And xml
<view
class="com.tr.search.SearchEditText"
android:id="@+id/search_src_text"
android:layout_height="wrap_content"
android:layout_width="0dip"
android:layout_weight="1.0"
android:singleLine="true"
android:ellipsize="end"
android:hint="@string/search_bar_hint"
android:drawableLeft="@drawable/magnifying_glass"
android:freezesText="true"
/>
Result
Your should look at the official documentation : http://d.android.com/guide/topics/search/search-dialog.html
well first you have to make your textView clickable with following code
TextView txtView =findViewById(R.id.txtView);
txtView.setOnClickListener(new OnClickListener(View v){
new OnClickListener() {
@Override
public void onClick(View v) {
//Your Code for calling search ativity
}
});
for search activity plz refer here
there is also one example given for search dialog in android sdk if you are using eclipse, then just click on
File->new->android Project->select sdk
->create project from existing project sample
select searchableDictionary
