/** * Created by Administrator on 2016/6/16. */ public class MyDialog extends Dialog { public MyDialog(Context context, View layout) { super(context); setContentView(layout); getWindow().setBackgroundDrawable(new BitmapDrawable()); // 其实这条蓝色的线条叫做titleDiver，去掉方法如下 try { int dividerID = context.getResources().getIdentifier("android:id/titleDivider", null, null); View divider = findViewById(dividerID); divider.setBackgroundColor(Color.TRANSPARENT); } catch (Exception e) { //上面的代码，是用来去除Holo主题的蓝色线条 e.printStackTrace(); } } } 2调用MyDialog // 选择是否更新 private void methodSelectUpdate() { View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.dialog_version_update, null); final MyDialog dialogDeleteOrder = new MyDialog(MainActivity.this, view); dialogDeleteOrder.setCanceledOnTouchOutside(false); dialogDeleteOrder.setCancelable(false); dialogDeleteOrder.show(); TextView tvContent= (TextView) view.findViewById(R.id.tvContent); // tvContent.setText(content); // 取消 TextView tvCancel = (TextView) view.findViewById(R.id.tvCancel); tvCancel.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (dialogDeleteOrder.isShowing()) { dialogDeleteOrder.dismiss(); } } }); // 确定 TextView tvServiceCall = (TextView) view.findViewById(R.id.tvServiceCall); tvServiceCall.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (dialogDeleteOrder.isShowing()) { dialogDeleteOrder.dismiss(); } } }); } 3MyDialog的布局文件dialog_version_update.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center_horizontal" android:orientation="vertical"> <LinearLayout android:layout_width="260dp" android:layout_height="wrap_content" android:background="@drawable/buttonstyle_sercice_call" android:orientation="vertical"> <LinearLayout android:layout_margin="2dp" android:layout_width="match_parent" android:layout_height="85dp" android:background="#FFFFFF" android:gravity="center" android:orientation="vertical"> <TextView android:layout_marginTop="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="发现新版本" android:textSize="18sp" android:textColor="#000000" /> <TextView android:id="@+id/tvContent" android:textSize="18sp" android:textColor="#000000" android:layout_marginTop="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> <ImageView android:layout_width="match_parent" android:layout_height="1dp" android:background="#E1E1E1" /> <LinearLayout android:layout_width="match_parent" android:layout_height="42dp" android:background="#FFFFFF" android:orientation="horizontal"> <TextView android:id="@+id/tvCancel" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_margin="1dp" android:layout_weight="1" android:background="@drawable/recycler_bg_but" android:text="取消" android:gravity="center" /> <ImageView android:layout_width="0.5dp" android:layout_height="match_parent" android:background="#E1E1E1" /> <TextView android:id="@+id/tvServiceCall" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_margin="1dp" android:layout_weight="1" android:background="@drawable/recycler_bg_but" android:text="更新" android:gravity="center" /> </LinearLayout> </LinearLayout> </LinearLayout> 源码下载：MyApplication02----app
