将透明背景设置为android中的alertdialog

在此输入图像描述

我想用透明背景显示警告对话框.我的警报对话框代码是:

AlertDialog.Builder imageDialog = new AlertDialog.Builder(SubProducts.this);
LayoutInflater inflater = (LayoutInflater)SubProducts.this.getSystemService(LAYOUT_INFLATER_SERVICE);

View layout = inflater.inflate(R.layout.cust_toast_layout,(ViewGroup)findViewById(R.id.linearLayout2));

ImageView image = (ImageView)layout.findViewById(R.id.imageView1);
image.setPadding(0, 20, 0, 0);
imgLoader.DisplayImage(image_url, loader, image);


TextView tprice=(TextView)layout.findViewById(R.id.pricetext);
tprice.setText("$ "+pricedouble);

TextView tvdprh=(TextView)layout.findViewById(R.id.textView1);

tvdprh.setText(prohd);




WebView wv=(WebView)layout.findViewById(R.id.webview);



Spanned sub=Html.fromHtml(descp);
String s = "<html><head><style type='text/css' >@font-face {font-family:'myfont';src: url('file:///android_asset/fonts/ABeeZee-Regular.ttf');}body {margin:0px;color:000000;font-family: myfont;"
        + "text-align: justify;}</style></head><body>"
        + sub

wv.loadDataWithBaseURL("", s, "text/html", "utf-8", null);
wv.setVerticalScrollBarEnabled(true);
wv.setBackgroundColor(Color.TRANSPARENT);
wv.setPadding(5, 25, 5, 0);

issue:指定的子级已有父级.您必须首先在孩子的父母上调用removeView()

我开发应用程序以将动态数据添加到多个表视图.结构如下.

在此输入图像描述我在onPostExecute中的代码是:

    protected void onPostExecute(List<String> results){
int ind,i = 0;
ScrollView sv=null;
TableLayout tl=null;
TableRow tr = null;
int mjsonlength=results.size();
if(results!=null){

 TableLayout indextl=(TableLayout)findViewById(R.id.indextablelayout);
    TableRow indextr=new TableRow(SubProducts.this);
    //indext1.moveToFirst();
    LinearLayout llt=(LinearLayout)findViewById(R.id.alltablell);
    //for(int f=0;f<mjsonlength;f++){

        for( ind=0;ind<indextitle.size();ind++)
        {

            TextView indextv=new TextView(SubProducts.this);
            indextv.setBackgroundResource(R.drawable.greenbg);
            indextv.setHeight(25);
            indextv.setWidth(50);
            indextv.setId(6);
            indextv.setTextColor(Color.WHITE);
            indextv.setText(indextitle.get(ind));
            indextv.setPadding(20,10,6,3);
            indextr.addView(indextv);

            indextl.addView(indextr,6);

            sv=new ScrollView(SubProducts.this);
             tl=new TableLayout(SubProducts.this);
             for( i=0;i<mjsonlength;i++){
                    tr=new TableRow(SubProducts.this);

                    if(ind==i)  {

                        RelativeLayout rl=new RelativeLayout(SubProducts.this);
                        Resources res = getResources(); //resource handle
                          rl.setBackgroundResource(R.drawable.prd_box);

                         RelativeLayout.LayoutParams newParams1 = new RelativeLayout.LayoutParams(
                                    RelativeLayout.LayoutParams.WRAP_CONTENT,
                                    RelativeLayout.LayoutParams.WRAP_CONTENT);

                            image=new ImageView(SubProducts.this);
                            image.setLayoutParams(newParams1);
                            image.setId(1);
                            image.setImageBitmap(bmp);
                            image.setPadding(5, 20, …

我尝试过这段代码:

ImageView img=(ImageView)findViewById(R.id.imageView1);
Random rand = new Random();
int rndInt = rand.nextInt(52) + 1;
String drawableName = "photo"+ rndInt;

int resID = getResources().getIdentifier(drawableName, "drawable",  getPackageName());
img.setImageResource(resID);
