1.BitmapDrawable
①XML定义BitmapDrawable:
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:dither="true"
android:src="@drawable/ic_launcher"
android:tileMode="mirror" />
②实现相同效果的Java代码:
BitmapDrawable bitDrawable = new BitmapDrawable(bitmap);
bitDrawable.setDither(true);
bitDrawable.setTileModeXY(TileMode.MIRROR,TileMode.MIRROR);

2.InsetDrawable
①XML中使用:
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@drawable/test1"
android:insetBottom="10dp"
android:insetLeft="10dp"
android:insetRight="10dp"
android:insetTop="10dp" />
②在Java代码中使用：
InsetDrawable insetDrawable = new InsetDrawable(getResources()
.getDrawable(R.drawable.test1), 10, 10, 10, 10);

3.ClipDrawable
①定义一个ClipDrawable的资源xml:
<clip xmlns:android="http://schemas.android.com/apk/res/android"
android:clipOrientation="horizontal"
android:drawable="@mipmap/ic_bg_meizi"
android:gravity="left" />
②在activity_main主布局文件中设置一个ImageView,将src设置为clipDrawable! 记住是src哦,如果你写成了blackground的话可是会报空指针的哦!!!!
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="@+id/img_show"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/clip_bg" />
</LinearLayout>
③MainActivity.java通过setLevel设置截取区域大小:
public class MainActivity extends AppCompatActivity {
private ImageView img_show;
private ClipDrawable cd;
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
if (msg.what == 0x123) {
cd.setLevel(cd.getLevel() + 500);
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img_show = (ImageView) findViewById(R.id.img_show);
// 核心实现代码
cd = (ClipDrawable) img_show.getDrawable();
final Timer timer = new Timer();
timer.schedule(new TimerTask() {
@Override
public void run() {
handler.sendEmptyMessage(0x123);
if (cd.getLevel() >= 10000) {
timer.cancel();
}
}
}, 0, 300);
}
}

4.RotateDrawable

①定义一个
rotateDrawable资源文件:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@mipmap/ic_launcher"
android:fromDegrees="-180"
android:pivotX="50%"
android:pivotY="50%" />
②activity_main.xml中修改下src指向上述drawable即可,MainActivity只需要把ClipDrawable 改成rotateDrawable即可!
public class MainActivity extends AppCompatActivity {
private ImageView img_show;
private RotateDrawable cd;
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
if (msg.what == 0x123) {
if (cd.getLevel() >= 10000)
Toast.makeText(MainActivity.this, "转完了~",
Toast.LENGTH_LONG).show();
cd.setLevel(cd.getLevel() + 400);
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img_show = (ImageView) findViewById(R.id.img_show);
// 核心实现代码
cd = (RotateDrawable) img_show.getDrawable();
final Timer timer = new Timer();
timer.schedule(new TimerTask() {
@Override
public void run() {
handler.sendEmptyMessage(0x123);
if (cd.getLevel() >= 10000) {
timer.cancel();
}
}
}, 0, 100);
}
}

5.AnimationDrawable
代码实现：
①先定义一个AnimationDrawable的xml资源文件:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false">
<item
android:drawable="@mipmap/ic_pull_to_refresh_loading01"
android:duration="100" />
<item
android:drawable="@mipmap/ic_pull_to_refresh_loading02"
android:duration="100" />
<item
android:drawable="@mipmap/ic_pull_to_refresh_loading03"
android:duration="100" />
<item
android:drawable="@mipmap/ic_pull_to_refresh_loading04"
android:duration="100" />
<item
android:drawable="@mipmap/ic_pull_to_refresh_loading05"
android:duration="100" />
<item
android:drawable="@mipmap/ic_pull_to_refresh_loading06"
android:duration="100" />
</animation-list>
②activity_main.xml设置下src,然后MainActivity中:
public class MainActivity extends AppCompatActivity {
private ImageView img_show;
private AnimationDrawable ad;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img_show = (ImageView) findViewById(R.id.img_show);
// 核心实现代码
ad = (AnimationDrawable) img_show.getDrawable();
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
ad.start();
}
}, 300);
}
}

1.LayerDrawable
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<bitmap
android:gravity="center"
android:src="@mipmap/ic_bg_ciwei" />
</item>
<item
android:left="25dp"
android:top="25dp">
<bitmap
android:gravity="center"
android:src="@mipmap/ic_bg_ciwei" />
</item>
<item
android:left="50dp"
android:top="50dp">
<bitmap
android:gravity="center"
android:src="@mipmap/ic_bg_ciwei" />
</item>
</layer-list>
然后在activity_main.xml里加个ImageView，内容如下：
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/layerlist_two"/>
image
TransitionDrawable
实现代码：
在res/drawable创建一个TransitionDrawable的xml文件
<?xml version="1.0" encoding="utf-8"?>
<transition xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@mipmap/ic_bg_meizi1"/>
<item android:drawable="@mipmap/ic_bg_meizi2"/>
</transition>
然后布局文件里加个ImageView，然后把src设置成上面的这个drawable 然后MainActivity.java内容如下：
public class MainActivity extends AppCompatActivity {
private ImageView img_show;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img_show = (ImageView) findViewById(R.id.img_show);
TransitionDrawable td = (TransitionDrawable) img_show.getDrawable();
td.startTransition(3000);
//你可以可以反过来播放，使用reverseTransition即可~
//td.reverseTransition(3000);
}
}
image
LevelListDrawable
代码实现：
通过shapeDrawable画圆，一式五份，改下宽高即可：
shape_cir1.xml：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#2C96ED"/>
<size android:height="20dp" android:width="20dp"/>
</shape>
接着到LevelListDrawable，这里我们设置五层：
level_cir.xml：
<?xml version="1.0" encoding="utf-8"?>
<level-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="@drawable/shape_cir1" android:maxLevel="2000"/>
<item android:drawable="@drawable/shape_cir2" android:maxLevel="4000"/>
<item android:drawable="@drawable/shape_cir3" android:maxLevel="6000"/>
<item android:drawable="@drawable/shape_cir4" android:maxLevel="8000"/>
<item android:drawable="@drawable/shape_cir5" android:maxLevel="10000"/>
</level-list>
最后MainActivity写如下代码：
public class MainActivity extends AppCompatActivity {
private ImageView img_show;
private LevelListDrawable ld;
private Handler handler = new Handler() {
public void handleMessage(Message msg) {
if (msg.what == 0x123) {
if (ld.getLevel() > 10000) ld.setLevel(0);
img_show.setImageLevel(ld.getLevel() + 2000);
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img_show = (ImageView) findViewById(R.id.img_show);
ld = (LevelListDrawable) img_show.getDrawable();
img_show.setImageLevel(0);
new Timer().schedule(new TimerTask() {
@Override
public void run() {
handler.sendEmptyMessage(0x123);
}
}, 0, 100);
}
}
