Android开发之自定义对话框（2）—加入EditText
由于项目需要，在弹出的对话框中要有编辑框，先看效果图：
1，先看布局文件：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="240dp"
android:layout_height="wrap_content"
android:background="@drawable/dialog_bkg_2"
android:orientation="vertical">
<TextView
android:id="@+id/dialog_title"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="@drawable/dialog_title_bkg"
android:gravity="center"
android:paddingBottom="4dp"
android:paddingTop="4dp"
android:textColor="@color/white"
android:text="@string/add_friend"
android:textSize="20sp" />
<EditText
android:id="@+id/edt_dialog_message"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:padding="4dp"
android:hint="请输入新好友用户名"
android:background="@drawable/dialog_bkg_edit"
android:textColor="@drawable/radio_btn_text"
android:textSize="18sp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="35dp"
android:layout_marginBottom="16dp"
android:orientation="horizontal">
<Button
android:id="@+id/btn_dialog_ok"
style="@style/btn_style"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_weight="1"
android:text="@string/button_add"
android:background="@drawable/button_selector"
android:textColor="@color/white"
android:textAllCaps="false"
android:textSize="18sp" />
<Button
android:id="@+id/btn_dialog_cancel"
style="@style/btn_style"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_weight="1"
android:text="@string/button_cancel"
android:background="@drawable/button_selector"
android:textColor="@color/white"
android:textAllCaps="false"
android:textSize="18sp" />

3，如何使用：
private void addFirend() {
final CustomDialog.Builder builder = new CustomDialog.Builder(getActivity());
builder.setTitle("添加好友");
builder.setPositiveButton("添加", new DialogInterface.OnClickListener() {
@Override
public void onClick(final DialogInterface dialog, int which) {
new Thread() {
@Override
public void run() {
String friendName = builder.getFriendName();
try{
EMClient.getInstance().contactManager().addContact(friendName,"我是你的朋友");
}catch (Exception e) {
e.printStackTrace();
}
}
}.start();
dialog.dismiss();
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builder.create().show();
}
