Android-----Change Icon original color and search box

This blog is mainly about the following two points of knowledge

icon Change color :drawable, so that Android can also have iOS so convenient image tone conversion, like the same icon, but there are many places to use, and the color is different, you can use this method.

Search Box: General is edittext realization, this article realizes TextView picture and text Center, the keyboard searches.

Take a look at:

icon Change color: The first interface to the left (two-dimensional code) and the right (more) two implementations, I put in the picture is black, showing that it is white.

Search box: The first interface of the picture and Text center, you can also set the spacing, the second meet search set the keyboard search button, click the Search listener events, clear the contents of the icon.

Search Box layout:

<!--Search icon Settings left android:drawableleft= "@mipmap/icon_search" android:drawablepadding= "5DP"            icon and text spacing to the right android:drawableright= "@mipmap/round_close" android:paddingright= "8DP" Android:imeoptions= "Actionsearch" set to search button -       <EditTextAndroid:id= "@+id/search_text"Android:layout_width= "0DP"Android:layout_weight= "1"Android:layout_height= "30DP"Android:hint= "Enter the item to search"Android:background= "@drawable/search_gray"Android:layout_margintop= "10DP"Android:layout_marginleft= "9DP"android:textsize= "12SP"Android:drawableleft= "@mipmap/icon_search"Android:paddingleft= "9DP"android:drawablepadding= "5DP"Android:drawableright= "@mipmap/round_close"Android:paddingright= "8DP"android:imeoptions= "Actionsearch"Android:maxlines= "1"Android:singleline= "true"          />              

Keyboard monitoring:

Searchtext.setoneditoractionlistener (NewTextview.oneditoractionlistener () {@Override Public BooleanOneditoraction (TextView V,intActionId, KeyEvent event) {                if((ActionId = = 0 | | actionid = = 3) && Event! =NULL) {
　　　　　　　　　　　　　// prompt search content  Toast.maketext (searchactivity. This, Searchtext.gettext (). toString (), Toast.length_long). Show (); //can jump to search page                   /*Intent intent= New Intent (Searchactivity.this,searchwebviewactivity.class);                    Intent.putextra ("model", model);                    Intent.putextra ("Search", Searchtext.gettext (). toString ());                    StartActivity (Intent); Finish ();*/                }                return false; }        });

Home layout:

<LinearLayoutAndroid:layout_width= "Match_parent"Android:layout_height= "Wrap_content"Android:background= "@color/colorprimary"Android:minheight= "45DP"android:orientation= "Horizontal"android:gravity= "Center_vertical"        >        <ImageButtonAndroid:id= "@+id/home_left_scan"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:paddingright= "19DP"Android:paddingtop= "3DP"Android:paddingbottom= "3DP"Android:paddingleft= "11DP"android:layout_centervertical= "true"Android:background= "#00000000"            />        <com. Zhangqie.searchbox.view.DrawableTextView Android:id= "@+id/home_search"Android:layout_width= "Match_parent"Android:layout_height= "28DP"Android:layout_weight= "1"Android:background= "@drawable/search_view_background"android:gravity= "Center_vertical"Android:maxlines= "1"Android:text= "Enter search related content"Android:drawableleft= "@mipmap/icon_search"android:textsize= "12SP"android:drawablepadding= "11DP"            />        <ImageButtonAndroid:id= "@+id/home_right_more"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"android:layout_centervertical= "true"Android:layout_alignparentright= "true"Android:paddingright= "15DP"Android:paddingtop= "3DP"Android:paddingbottom= "3DP"Android:paddingleft= "15DP"Android:background= "#00000000"            />    </LinearLayout>

Custom Drawabletextview: (center text icon)

 Public classDrawabletextviewextendsTextView { PublicDrawabletextview (Context context, AttributeSet attrs,intDefstyle) {        Super(context, attrs, Defstyle); }     PublicDrawabletextview (Context context, AttributeSet attrs) {Super(context, attrs); }     PublicDrawabletextview (Context context) {Super(context); } @Overrideprotected voidOnDraw (canvas canvas) {drawable[] drawables=Getcompounddrawables (); //get the Drawable object set by Drawableleftdrawable leftdrawable = drawables[0]; if(Leftdrawable! =NULL) {            //get the width of the leftdrawable            intLeftdrawablewidth =leftdrawable.getintrinsicwidth (); //get the spacing between drawable and text            intDrawablepadding =getcompounddrawablepadding (); //get the width of the text            intTextWidth = (int) Getpaint (). Measuretext (GetText (). toString (). Trim ()); intBodywidth = leftdrawablewidth + drawablepadding +TextWidth;            Canvas.save (); Canvas.translate ((getwidth ()-Bodywidth)/2, 0); }        Super. OnDraw (canvas); }}
