1 , Dialog布局

<?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="wrap_content"
    android:background="@drawable/dialog_bg"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/title"                     //标题
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:paddingTop="14dp"
        android:textColor="@color/login_hint"
        android:textSize="@dimen/text_size_18" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="14dp"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="30dp" >

        <TextView
            android:id="@+id/confirm"           //确认
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginRight="10dp"
            android:layout_weight="1"
            android:background="@drawable/btn_confirm_selector"
            android:gravity="center"
            android:textColor="@color/white"
            android:textSize="@dimen/text_size_16" />

        <TextView                 
            android:id="@+id/cancel"        //取消
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_weight="1"
            android:background="@drawable/btn_cancel_selector"
            android:gravity="center"
            android:textColor="@color/login_hint"
            android:textSize="@dimen/text_size_16" />
    </LinearLayout>

</LinearLayout>

2, 自己定义dialog 类

public class ConfirmDialog extends Dialog {

    private Context context;
    private String title;
    private String confirmButtonText;
    private String cacelButtonText;
    private ClickListenerInterface clickListenerInterface;

    public interface ClickListenerInterface {

        public void doConfirm();

        public void doCancel();
    }

    public ConfirmDialog(Context context, String title, String confirmButtonText, String cacelButtonText) {
        super(context, R.style.MyDialog);     //  定义的是样式 , 占时省略
        this.context = context;
        this.title = title;
        this.confirmButtonText = confirmButtonText;
        this.cacelButtonText = cacelButtonText;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        init();
    }

    public void init() {
        LayoutInflater inflater = LayoutInflater.from(context);
        View view = inflater.inflate(R.layout.confirm_dialog, null);
        setContentView(view);

        TextView tvTitle = (TextView) view.findViewById(R.id.title);
        TextView tvConfirm = (TextView) view.findViewById(R.id.confirm);
        TextView tvCancel = (TextView) view.findViewById(R.id.cancel);

        tvTitle.setText(title);
        tvConfirm.setText(confirmButtonText);
        tvCancel.setText(cacelButtonText);

        tvConfirm.setOnClickListener(new clickListener());
        tvCancel.setOnClickListener(new clickListener());

        Window dialogWindow = getWindow();
        WindowManager.LayoutParams lp = dialogWindow.getAttributes();
        DisplayMetrics d = context.getResources().getDisplayMetrics(); // 获取屏幕宽、高用
        lp.width = (int) (d.widthPixels * 0.8); // 高度设置为屏幕的0.6
        dialogWindow.setAttributes(lp);
    }

    public void setClicklistener(ClickListenerInterface clickListenerInterface) {
        this.clickListenerInterface = clickListenerInterface;
    }

    private class clickListener implements View.OnClickListener {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            int id = v.getId();
            switch (id) {
            case R.id.confirm:
                clickListenerInterface.doConfirm();
                break;
            case R.id.cancel:
                clickListenerInterface.doCancel();
                break;
            }
        }
    };
}

3 ,使用

public static void Exit(final Context context) {
        final ConfirmDialog confirmDialog = new ConfirmDialog(context, "确定要退出吗?", "退出", "取消");
        confirmDialog.show();
        confirmDialog.setClicklistener(new ConfirmDialog.ClickListenerInterface() {
            @Override
            public void doConfirm() {
                // TODO Auto-generated method stub
                confirmDialog.dismiss();     // 关闭
                //toUserHome(context);
                AppManager.getAppManager().AppExit(context);       //退出
            }

            @Override
            public void doCancel() {
                // TODO Auto-generated method stub
                confirmDialog.dismiss();
            }
        });
    }
