Android动态布局（TextView-drawableLeft）

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);
 
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);
