Android 自定义AlertDialog 并且4个角为圆角

//自定义AlertDialogLayoutInflater inflater = getLayoutInflater();View view1 = inflater.inflate(R.layout.dialog_activity, null);ImageView ivguanbi = view1.findViewById(R.id.iv_guanbi);TextView wjmm = view1.findViewById(R.id.tv_wjmm);EditText namephone = view1.findViewById(R.id.et_namephone);EditText newpassword = view1.findViewById(R.id.et_newpassword);EditText yanzhenma = view1.findViewById(R.id.yanzhenma);Button cxhqyzm = view1.findViewById(R.id.btn_nxhqyzm);//给textview字体加粗TextPaint paint = wjmm.getPaint();paint.setFakeBoldText(true);显示AlertDialogAlertDialog dialog = new AlertDialog.Builder(this)        .setView(view1)        .show();//给AlertDialog设置4个圆角dialog.getWindow().setBackgroundDrawableResource(R.drawable.dialogbg);

设置dialogbg或者说设置圆角并填充背景色或者说设置shape<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android">    <corners android:radius="30dp" />    <solid android:color="@color/colorWhite" />shape>

AlertDialog自定义xml布局代码如下：

<?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:background="@drawable/dialogbg"    android:orientation="vertical"    android:padding="30dp">    <ImageView        android:id="@+id/iv_guanbi"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="right"        android:src="@mipmap/btn_close" />    <TextView        android:id="@+id/tv_wjmm"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginBottom="20dp"        android:gravity="center"        android:text="忘记密码"        android:textColor="@color/colorBlack"        android:textSize="25sp" />    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:text="用户名："        android:textSize="12sp" />    <EditText        android:id="@+id/et_namephone"        android:layout_width="match_parent"        android:layout_height="30dp"        android:layout_marginBottom="10dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:background="@drawable/list_insert"        android:gravity="center"        android:hint="注册所用手机号" />    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:text="新密码："        android:textSize="12sp" />    <EditText        android:id="@+id/et_newpassword"        android:layout_width="match_parent"        android:layout_height="30dp"        android:layout_marginBottom="10dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:background="@drawable/list_insert"        android:gravity="center"        android:inputType="textPassword" />    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:gravity="center"        android:text="验证码："        android:textSize="12sp" />    <EditText        android:id="@+id/yanzhenma"        android:layout_width="match_parent"        android:layout_height="30dp"        android:layout_marginBottom="20dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:background="@drawable/list_insert"        android:gravity="center" />    <Button        android:id="@+id/btn_nxhqyzm"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/bg"        android:text="从新或取验证码"        android:textColor="@color/colorWhite" />LinearLayout>
