Use of Androidimageview

Configuration of XML Files <imageview     android:id= "@+id/imageviewid"      Android:layout_width= "100DP"     android:layout_height= "100DP"      android:src= "@drawable/a0"     android:background= "#ff0000"     android: Scaletype= "center"     /><imageview     android:id= "@+id/ ImageView2 "   android:layout_width=" 100DP "    android:layout_height=" 100DP "     android:background= "#00ff00"     android:src= "@drawable/ic_launcher "    android:scaletype="     />     "Fitcenter"     //mainactivity file     public class MainActivity  extends activity {private imageview imageview;private imageview imageview1;      @Override &NBsp;   protected void oncreate (bundle savedinstancestate)  {         super.oncreate (savedinstancestate);         setcontentview (R.layout.activity_main);         imageview= ( ImageView) Findviewbyid (R.ID.IMAGEVIEWID);       //  Imageview.setimageresource (R.DRAWABLE.A0);         imageview1= ( ImageView) Findviewbyid (R.ID.IMAGEVIEW2);         imageview.setscaletype (Scaletype.center);         imageview1.setscaletype (ScaleType.FIT_ CENTER);            }                 //description of the ScaleType property    //  imageview's scaletype determines what the image looks like when it is displayed on the view, such as the scaleand show the picture///The whole or part of the piece, etc. The way to set up includes://1.  defining android:scaletype= "CENTER"//2.  in Layout xml or calling Imageview.setscaletype in code ( ImageView.ScaleType.CENTER);

1. Setscaletype (ImageView.ScaleType.CENTER);

Centered on the original size of the picture, when the picture is longer/wider than the length/width of the view, the center portion of the image is displayed

650) this.width=650; "src=" Http://hi.csdn.net/attachment/201110/30/0_1319980238S0ht.gif "style=" border:none; Font-family:arial;font-size:14px;line-height:26px;white-space:normal;background-color:rgb (255,255,255); "/> 650) this.width=650; "src=" Http://hi.csdn.net/attachment/201110/30/0_1319980257h8NT.gif "style=" bo Rder:none;font-family:arial;font-size:14px;line-height:26px;white-space:normal;background-color:rgb ( 255,255,255); "/>

2. Setscaletype (ImageView.ScaleType.CENTER_CROP);

Proportionally enlarges the size of the image so that the image is long (wide) equal to or greater than the length (width) of the view

650) this.width=650; "src=" Http://hi.csdn.net/attachment/201110/30/0_1319980210oDm8.gif "style=" border:none; "/ > 650) this.width=650; "src=" http://hi.csdn.net/attachment/201110/30/0_13199802252Hvf.gif "style=" border: none; "/>

3. Setscaletype (ImageView.ScaleType.CENTER_INSIDE);

Center the contents of the picture in full, by scaling it down or the original size to make the picture long/wide equal to or less than the length/width of the view

650) this.width=650; "src=" Http://hi.csdn.net/attachment/201110/30/0_1319980180mJsK.gif "style=" border:none; "/ > 650) this.width=650; "src=" http://hi.csdn.net/attachment/201110/30/0_1319980194fb0b.gif "style=" border: none; "/>

4. Setscaletype (ImageView.ScaleType.FIT_CENTER);

Enlarges/shrinks the image to the width of the view, centered on the display

650) this.width=650; "src=" Http://hi.csdn.net/attachment/201110/30/0_1319980150BcCh.gif "style=" border:none; "/ > 650) this.width=650; "src=" http://hi.csdn.net/attachment/201110/30/0_13199801347auQ.gif "style=" border: none; "/>

5. Fit_start, fit_end in the picture zoom effect and fit_center, just show the location of different, Fit_start is placed on the top, Fit_center Center, fit_end at the bottom.

There is no example to show here.

6. Fit_xy

Do not scale the picture proportionally, the goal is to fill the picture with the entire view.

650) this.width=650; "src=" Http://hi.csdn.net/attachment/201110/30/0_1319980055JRlc.gif "height=" 402 "width=" 244 " Style= "border:none;width:244px;height:402px;"/> 650) this.width=650; "Src=" http://hi.csdn.net/attachment /201110/30/0_1319980073vf07.gif "height=" 402 "width=" 243 "style=" border:none;width:243px;height:402px; "/>
