Android開發修改DialogFragment樣式以及與activity之間的數據傳遞

很多時候出現在使用DialogFragment的時候,系統給定的樣式不能滿足我們的要求,因此我們就需要修改,其實修改其樣式非常的簡單,只需要填充佈局就可以了..

一,創建class繼承DialogFragment

public class AppDialog extends AppCompatDialogFragment 

二,重新onCreateDialog方法,並填充自己需要的DialogFragment樣式的佈局文件

    private Button bt_confirm;
    private Button bt_cancel;
    private ViewPager dg_viewpager;
    private TextView dg_title;

 @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View view = inflater.inflate(R.layout.dialog_add_picture, null);
        bt_confirm = (Button) view.findViewById(R.id.dialog_confirm);//確認按鈕
        bt_cancel = (Button) view.findViewById(R.id.dialog_cancel);//取消按鈕
        dg_viewpager = (ViewPager) view.findViewById(R.id.dialog_viewpager);//dialog內容
        dg_title = (TextView) view.findViewById(R.id.dialog_title);//dialog標題
        initListener();
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setView(view);
        return builder.create();

    }
佈局文件:
<?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="wrap_content"
    android:minWidth="280dip"
    android:orientation="vertical">

    <TextView
        android:id="@+id/dialog_title"
        android:layout_width="match_parent"
        android:layout_height="64dp"
        android:gravity="center"
        android:text="添加方式"
        android:textColor="#464646"
        android:textSize="32dp" />

    <android.support.v4.view.ViewPager
        android:id="@+id/dialog_viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />
    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="#BCBCBC" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <Button
            android:id="@+id/dialog_cancel"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:background="#FFF"
            android:gravity="center_horizontal"
            android:text="取消"
            android:textColor="#838383"
            android:textSize="32dp" />

        <View
            android:layout_width="1dp"
            android:layout_height="40dp"
            android:background="#BCBCBC" />

        <Button
            android:id="@+id/dialog_confirm"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:background="#FFF"
            android:gravity="center_horizontal"
            android:text="確認"
            android:textColor="#5896FE"
            android:textSize="32dp" />
    </LinearLayout>
</LinearLayout>

三,設置DialogFragment的取消/確認監聽事件,其中setCancelable(false);//設置點擊除dialog外(包括點擊返回鍵)不消失,setCanceledOnTouchOutside(false)設置點擊除dialog外(不包括點擊返回鍵)不消失

 private void initListener() {
        setCancelable(false);//設置點擊除dialog外(包括點擊返回鍵)不消失,setCanceledOnTouchOutside(false)設置點擊除dialog外(不包括點擊返回鍵)不消失
        bt_confirm.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(), "確認", Toast.LENGTH_SHORT).show();
            }
        });
        bt_cancel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(), "取消", Toast.LENGTH_SHORT).show();
                dismiss();
            }
        });
    }

四,設置dialog邊框爲透明色

  /**
     * 內邊框設置背景爲透明色
     *
     * @param inflater
     * @param container
     * @param savedInstanceState
     * @return
     */
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        return super.onCreateView(inflater, container, savedInstanceState);
    }


/* * 
*外邊框設置透明色
*/
    @Override
    public void onStart() {
        super.onStart();
        Window window = getDialog().getWindow();
        WindowManager.LayoutParams windowParams = window.getAttributes();
        windowParams.dimAmount = 0.0f;
        window.setAttributes(windowParams);
    }

五,Activity顯示dialog顯示以及activity傳遞數據到dialogFragment,數據傳遞通過bundle傳遞.

/**
*activity傳遞數據給dialogFragment
*/
  AppDialog appDialog = new AppDialog();
    Bundle bundle = new Bundle();
   bundle.putString("flag","string");
    appDialog .setArguments(bundle);   //設置dialog的bundle appDialog.show(getSupportFragmentManager(),"appIcon");//顯示fragmentdialog

/**
*dialogFragment接收數據
*/

@Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bundle bundle = getArguments();
       String str= bundle.getString("flag");
        System.out.print(str)
    }

六,從dialogFragment傳遞數據到activity使用回調接口.

/**
*dialogFragment中書寫接口
*/
 public interface DialogClickListener{
       void onDialoClick();
    }
    public void setOnDialogClick(DialogClickListener listener){
        this.listener=listener;
    }
/**
*activity中實現接口方法
*/
  dialog.setOnDialogClick(new AchiviementDialog.DialogClickListener() {
            @Override
            public void onDialoClick() {
                System.out.print("我是點擊事件")
            }
        });
