Android动态布局，并动态为TextView控件设置drawableLeft、drawableRight等属性加入图标

注：(图中每个条目和图标都是由代码动态生成)

代码动态布局，并须要为每个条目设置图标，此时用到了 android:drawableLeft="@drawable/icon" 

父xml文件：

[html] view
plaincopyprint

" style="color:rgb(160,160,160); text-decoration:none; background-color:inherit; border:none; padding:0px; margin:0px 10px 0px 0px; font-size:9px">?

1. <?

   xml version="1.0" encoding="utf-8"?>

2. <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
3. android:layout_width="match_parent"
4. android:layout_height="match_parent"
5. android:background="@color/background" >
6. <!-- 子布局由代码动态生成 -->
7. <LinearLayout
8. android:id="@+id/layout_CONTENT"
9. android:layout_width="match_parent"
10. android:layout_height="match_parent"
11. android:padding="@dimen/content_padding" >
12. <LinearLayout
13. android:id="@+id/activity_service_select"
14. android:layout_width="match_parent"
15. android:layout_height="wrap_content"
16. android:layout_margin="@dimen/table_margin"
17. android:background="@color/table_background"
18. android:orientation="vertical"
19. android:padding="@dimen/table_padding" >
20. </LinearLayout>
21. </LinearLayout>
22. </ScrollView>

子xml文件：

[html] view
plaincopyprint?

1. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
2. android:layout_width="match_parent"
3. android:layout_height="@dimen/row_height"
4. android:layout_marginBottom="@dimen/row_margin"
5. android:background="@drawable/row_selector"
6. android:paddingLeft="@dimen/row_padding_left"
7. android:paddingRight="@dimen/row_padding_right" >
8. <TextView
9. android:id="@+id/tv_select_item"
10. style="@style/text_18"
11. android:layout_width="match_parent"
12. android:layout_height="@dimen/row_height"
13. android:layout_marginBottom="@dimen/row_margin"
14. android:background="@drawable/row_selector"
15. android:gravity="center_vertical"
16. android:textColor="@drawable/row_text_selector" />
17. <ImageView
18. android:id="@+id/iv_icon"
19. android:layout_width="wrap_content"
20. android:layout_height="match_parent"
21. android:layout_alignParentRight="true"
22. android:duplicateParentState="true"
23. android:gravity="center_vertical"
24. android:src="@drawable/go" />
25. </RelativeLayout>

代码中引用：

[java] view
plaincopyprint?

1. private ViewGroup mLayout;
2. private int img[] = {R.drawable.zikao1,R.drawable.zikao2,R.drawable.zikao3,R.drawable.zikao4};
3. /* (non-Javadoc)
4. * @see app.ui.TitleActivity#onCreate(android.os.Bundle)
5. */
6. @Override
7. protected void onCreate(Bundle savedInstanceState) {
8. super.onCreate(savedInstanceState);
9. setUpViews();
10. }
11. private void setUpViews()
12. {
13. setContentView(R.layout.activity_service_select);
14. setTitle(R.string.text_select);
15. showBackwardView(R.string.button_backward, true);
16. mLayout = (ViewGroup)findViewById(R.id.activity_service_select);
17. final String [] mSelfSelect = getResources().getStringArray(R.array.text_self_select);
18. // 须要布局的行数
19. final int rowCount = mSelfSelect.length;
20. for (int i = 0; i < rowCount; i++) {
21. final LinearLayout linearLayout = new LinearLayout(this);
22. View.inflate(this, R.layout.service_examvaluable_item, linearLayout);
23. final View view = linearLayout.getChildAt(0);
24. view.setTag(i+1);
25. view.setOnClickListener(this);
26. Drawable drawable= getResources().getDrawable(img[i]);
27. drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
28. final TextView mTextView = (TextView) linearLayout.findViewById(R.id.tv_select_item);
29. mTextView.setCompoundDrawables(drawable,null,null,null);//设置TextView的drawableleft
30. mTextView.setCompoundDrawablePadding(10);//设置图片和text之间的间距
31. mTextView.setText(mSelfSelect[i]);
32. // 加入到屏幕布局
33. LayoutParams layoutParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT);
34. mLayout.addView(linearLayout, layoutParams);
35. }
36. }

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

解决方式：

[java] view
plaincopy

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

类似调用方法例如以下:

1.在XML中使用

[java] view
plaincopy

1. android:drawableLeft="@drawable/icon"

2.代码中动态变化

[java] view
plaincopy

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

參考还有一个函数：

[java] view
plaincopy

1. public void setCompoundDrawablesWithIntrinsicBounds (Drawable left,
2. Drawable top, Drawable right, Drawable bottom)
