Android动态布局，并动态为TextView控件设置drawableLeft、drawableRight等属性添加图标

注：(图中每一个条目和图标都是由代码动态生成)

代码动态布局，并需要为每一个条目设置图标，此时用到了 android:drawableLeft="@drawable/icon" 

父xml文件：

 <?xml version="1.0" encoding="utf-8"?>
 <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:background="@color/background" >
     <!-- 子布局由代码动态生成 -->
     <LinearLayout
         android:id="@+id/layout_CONTENT"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:padding="@dimen/content_padding" >

         <LinearLayout
             android:id="@+id/activity_service_select"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:layout_margin="@dimen/table_margin"
             android:background="@color/table_background"
             android:orientation="vertical"
             android:padding="@dimen/table_padding" >
         </LinearLayout>
     </LinearLayout>

 </ScrollView>

子xml文件：

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="@dimen/row_height"
     android:layout_marginBottom="@dimen/row_margin"
     android:background="@drawable/row_selector"
     android:paddingLeft="@dimen/row_padding_left"
     android:paddingRight="@dimen/row_padding_right" >

     <TextView
         android:id="@+id/tv_select_item"
         style="@style/text_18"
         android:layout_width="match_parent"
         android:layout_height="@dimen/row_height"
         android:layout_marginBottom="@dimen/row_margin"
         android:background="@drawable/row_selector"
         android:gravity="center_vertical"
         android:textColor="@drawable/row_text_selector" />

     <ImageView
         android:id="@+id/iv_icon"
         android:layout_width="wrap_content"
         android:layout_height="match_parent"
         android:layout_alignParentRight="true"
         android:duplicateParentState="true"
         android:gravity="center_vertical"
         android:src="@drawable/go" />

 </RelativeLayout>

代码中引用：

 private ViewGroup mLayout;
     private int img[] = {R.drawable.zikao1,R.drawable.zikao2,R.drawable.zikao3,R.drawable.zikao4};
     /* (non-Javadoc)
      * @see app.ui.TitleActivity#onCreate(android.os.Bundle)
      */
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setUpViews();
     }

     private void setUpViews()
     {
         setContentView(R.layout.activity_service_select);
         setTitle(R.string.text_select);
         showBackwardView(R.string.button_backward, true);
         mLayout = (ViewGroup)findViewById(R.id.activity_service_select);
         final String [] mSelfSelect = getResources().getStringArray(R.array.text_self_select);
         // 需要布局的行数
         final int rowCount = mSelfSelect.length;
         for (int i = 0; i < rowCount; i++) {
             final LinearLayout linearLayout = new LinearLayout(this);
             View.inflate(this, R.layout.service_examvaluable_item, linearLayout);
             final View view = linearLayout.getChildAt(0);
             view.setTag(i+1);
             view.setOnClickListener(this);

             Drawable drawable= getResources().getDrawable(img[i]);
             drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());

             final TextView mTextView = (TextView) linearLayout.findViewById(R.id.tv_select_item);
             mTextView.setCompoundDrawables(drawable,null,null,null);//设置TextView的drawableleft
             mTextView.setCompoundDrawablePadding(10);//设置图片和text之间的间距
             mTextView.setText(mSelfSelect[i]);
             // 添加到屏幕布局
             LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
             mLayout.addView(linearLayout, layoutParams);
         }
     }

在程序中直接取出子xml中TextView中的id，并动态设置改变了 DrawableLeft。

解决方案：

 public void  setCompoundDrawables  (Drawable left, Drawable top, Drawable right, Drawable bottom);

类似调用方法如下:

1.在XML中使用

 android:drawableLeft="@drawable/icon"

2.代码中动态变化

 Drawable drawable= getResources().getDrawable(R.drawable.drawable);
 drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
 myTextview.setCompoundDrawables(drawable,null,null,null);

参考另一个函数：

 public void setCompoundDrawablesWithIntrinsicBounds (Drawable left,
 Drawable top, Drawable right, Drawable bottom)
