1.在布局文件中设置图文混排

<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"    tools:context="com.example.androidbutton.MainActivity" >    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="vertical" >        <Button            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:drawableTop="@drawable/star"            android:text="button1" />        <Button            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:drawablePadding="30dp"            android:drawableRight="@drawable/star"            android:text="button2" />        <Button            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:drawablePadding="50dp"            android:drawableTop="@drawable/star"            android:text="button3" />        <Button            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:drawableLeft="@drawable/star"            android:drawableTop="@drawable/star"            android:text="button4" />    </LinearLayout>    <Button        android:id="@+id/button"        android:layout_width="200dp"        android:layout_height="200dp"        android:layout_margin="0dp"        android:text="kk" /></LinearLayout>

2.在java代码中设置图文混排

public class MainActivity extends ActionBarActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Button button = (Button) findViewById(R.id.button);SpannableString spannableStringLeft = new SpannableString("left");Bitmap bitmapLeft = BitmapFactory.decodeResource(getResources(),R.drawable.image_left);ImageSpan imageSpanLeft = new ImageSpan(bitmapLeft,DynamicDrawableSpan.ALIGN_BOTTOM);spannableStringLeft.setSpan(imageSpanLeft, 0, 4,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);SpannableString spannableStringRight = new SpannableString("right");Bitmap bitmapRight = BitmapFactory.decodeResource(getResources(),R.drawable.image_right);ImageSpan imageSpanRight = new ImageSpan(bitmapRight);spannableStringRight.setSpan(imageSpanRight, 0, 5,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);button.append(spannableStringLeft);button.append("我的按钮...");button.append(spannableStringRight);}}
