安卓 有关动态加载ImageView，Radiobutton

根据项目需求，想要动态加载控件，imageview，radiobutton

sample:

1.动态加载imageview

// 显示已有的图片， 计算图片数量

//这里imgs是图片的list数组

private void initPhotos(View v, HashMap<Integer, String> imgs) {

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(

(getWidthPx() - 12 * 2) / 3, (getWidthPx() - 20 * 2) / 4);

int imgCount = (imgs == null || imgs.size() == 0) ? 0 : (imgs.size() > 3 ? 3 : imgs.size());

for (int i = 0; i < imgCount; i++) {

ImageView img = (ImageView) v.findViewWithTag("img" + i);

MApplication.get().getImageLoader2().displayImage(imgs.get(i), img);

img.setVisibility(View.VISIBLE);

img.setLayoutParams(lp);

}

imgLayout1.setLayoutParams(lp);

imgLayout2.setLayoutParams(lp);

imgLayout3.setLayoutParams(lp);

}

xml文件

<LinearLayout

android:id="@+id/level_imglayout2d"

android:layout_width="0dp"

android:layout_height="wrap_content"

android:layout_weight="1"

android:background="@drawable/levelup_udlr"

android:gravity="center_vertical"

android:orientation="horizontal"

android:padding="3dp"

android:visibility="invisible" >

<ImageView

android:layout_width="match_parent"

android:layout_height="match_parent"

android:layout_marginLeft="2dp"

android:scaleType="fitXY"

android:tag="@+tag/img1" />

</LinearLayout>

sample2

动态加载radioButton

private RadioGroup rg;

protected void onInitLayout(View view) {

rg = (RadioGroup) view.findViewById(R.id.qualityRadioGroup);

rg.setOnCheckedChangeListener(this);

//在fragment中，使用shareedPreference添加临时数据更方便

sharePreference = LSharePreference.getInstance(getActivity());

//发送json

sendQualityConditionJson();

}

//动态 添加radiobutton

private void setData() {

for (int i = 0; i < mData.size(); i++) {

final RadioButton radioButton = new RadioButton(getActivity());

radioButton.setText(mData.get(i).name);

radioButton.setTextColor(Color.BLACK);

radioButton.setButtonDrawable(R.drawable.radio_button_selector);

radioButton.setPadding(55, 10, 10, 10);

radioButton.setTag(i);

radioButton.setId(3020 + i);

if(!LFormat.isEmpty(sharePreference.getString("QUALITY_CONDITION"))){

if (i == Integer.parseInt(sharePreference.getString("QUALITY_CONDITION"))-3020-2){

radioButton.setChecked(true);

}

}else if (i==0){

radioButton.setChecked(true);

}

rg.addView(radioButton);

radioButton.setOnClickListener(this);

}

rg.setOnCheckedChangeListener(this);

}

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

//这里把id，又减去了3020，得到的就是原始的list中的数据索引

sharePreference.setString("QUALITY_CONDITION",

mData.get(v.getId() - 3020).id + "");

L.e(sharePreference.getString("QUALITY_CONDITION", ""));

}
