推荐答案

custom_dialog.xml

custom_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >


    <EditText
        android:id="@+id/editText"
        android:hint="Enter some thing"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

    <requestFocus />
    </EditText>

    <LinearLayout                
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"   
        android:layout_marginTop="10dp">     

        <Button
            android:id="@+id/save"
            android:layout_marginTop="15dp"
            android:layout_weight="1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="SAVE" />

        <Button
            android:id="@+id/cancel"
            android:layout_marginTop="15dp"
            android:layout_weight="1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Cancel" />

    </LinearLayout>
</LinearLayout>

需要膨胀custom_dialog.xml

final Dialog dialog = new Dialog(this);

dialog.setContentView(R.layout.custom_dialog);
dialog.setTitle("Custom Alert Dialog");

final EditText editText = (EditText) dialog.findViewById(R.id.editText);
Button btnSave          = (Button) dialog.findViewById(R.id.save);
Button btnCancel        = (Button) dialog.findViewById(R.id.cancel);
dialog.show();
