Android自定义样式的对话框

首先看下效果图，确保是你想要的效果：

xml文件：

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:layout_gravity="center"      android:background="@drawable/pop_bg"      android:orientation="vertical" >        <TextView          android:id="@+id/title"          android:layout_width="fill_parent"          android:layout_height="40.0dip"          android:layout_marginTop="15dp"          android:gravity="center"          android:text="设置号码"          android:textColor="#fffffb"          android:textSize="20sp"          android:visibility="visible" />      <!--   <LinearLayout          android:id="@+id/contentView"          android:layout_width="fill_parent"          android:layout_height="wrap_content" > -->            <EditText              android:id="@+id/number"              android:layout_width="fill_parent"              android:layout_height="wrap_content"              android:layout_marginLeft="10dp"              android:layout_marginRight="10dp"              android:layout_marginTop="5dp"              android:gravity="left|center"              android:hint="号码" />      <!-- </LinearLayout> -->          <LinearLayout          android:layout_width="fill_parent"          android:layout_height="60.0dip"          android:layout_gravity="bottom"          android:layout_marginTop="5dp"          android:gravity="center"          android:orientation="horizontal" >            <Button              android:id="@+id/positiveButton"              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:background="@drawable/btn_ok_selector"              android:gravity="center" />            <Button              android:id="@+id/negativeButton"              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:layout_marginLeft="20.0dip"              android:background="@drawable/btn_cancel_selector"              android:gravity="center" />      </LinearLayout>    </LinearLayout>

 // 弹窗   private void dialog() {    dialog = new CustomDialog(WorkspaceActivity.this);    EditText editText = (EditText) dialog.getEditText();//方法在CustomDialog中实现    dialog.setOnPositiveListener(new OnClickListener() {     @Override     public void onClick(View v) {      //dosomething youself      dialog2.dismiss();     }    });    dialog.setOnNegativeListener(new OnClickListener() {     @Override     public void onClick(View v) {      dialog2.dismiss();     }    });    dialog.show();   }
