摘要：
AlertDialog.Builderbuilder=newBuilder(mContext);builder.setTitle("更新进度");finalLayoutInflaterinflater=LayoutInflater.from(mContext);Viewv=inflater.inflate(R.layout.progress,null);mProgress=(ProgressBar
AlertDialog.Builder builder = new Builder(mContext);
builder.setTitle("更新进度");
final LayoutInflater inflater = LayoutInflater.from(mContext);
View v = inflater.inflate(R.layout.progress, null);
mProgress = (ProgressBar) v.findViewById(R.id.progress);
builder.setView(v);//此处设置自定义布局
downloadDialog = builder.create();
downloadDialog.show();
downloadDialog.getWindow().setLayout(300, 200);//此处设置位置窗体大小
注意设置位置需要在dialog调用show()方法以后，要不然没有效果i改变
另外dialog也可以设置窗体位置 具体代码为
menuDialog = new AlertDialog.Builder(this).create();
Window mWindow = menuDialog.getWindow();
WindowManager.LayoutParams lp = mWindow.getAttributes();
lp.x = 10; //新位置X坐标
lp.y = 120; //新位置Y坐标
menuDialog.onWindowAttributesChanged(lp);
menuDialog.show();
