自定义DialogFragment

java代码部分

public class ChangePwdDialog extends DialogFragment {    private ChangePwdClickListener mListener;    @NonNull    @Override    public Dialog onCreateDialog(Bundle savedInstanceState) {        LayoutInflater layoutInflater = getActivity().getLayoutInflater();        View view = layoutInflater.inflate(R.layout.dialog_change_pwd, null);        TextView title = (TextView) view.findViewById(R.id.tv_go_change_pwd);

//设置dialog的style        Dialog dialog = new Dialog(getActivity(), R.style.dialog);        dialog.setContentView(view);        //对话框弹出后点击屏幕或按返回键不消失，设置为true则xianfan;        setCancelable(false);        //对话框弹出后点击屏幕不消失,按返回键消失，
        //setCanceledOnTouchOutside(false);
        title.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if(mListener!=null){                    mListener.changePwdCilck();                }                dismiss();            }        });        return dialog;    }//接口会调，设置点击事件    public void setClickListener( ChangePwdClickListener listener){        mListener = listener;    }    public interface ChangePwdClickListener {        void changePwdCilck();    }}

dilog的style部分

<style name="dialog" parent="@android:style/Theme.Dialog">    <!--边框-->    <item name="android:windowFrame">@null</item>    <!--是否浮现在activity之上-->    <item name="android:windowIsFloating">true</item>    <!--模糊-->    <item name="android:backgroundDimEnabled">true</item>    <!--半透明-->    <item name="android:windowIsTranslucent">true</item>    <!--无标题-->    <item name="android:windowNoTitle">true</item>    <!--背景透明-->    <item name="android:windowBackground">@android:color/transparent</item></style>

代码中调用

mChangePwdDialog = new ChangePwdDialog();mChangePwdDialog.setClickListener(new ChangePwdDialog.ChangePwdClickListener() {    @Override    public void changePwdCilck() {        startActivity(new Intent(MainActivity.this,ModifyPasswordActivity.class));    }});
if (mChangePwdDialog != null) {
//参数为，第一个是fragment的管理器，第二个是一个tag值，可随意设置    mChangePwdDialog.show(getSupportFragmentManager(), ChangePwdDialog.class.getSimpleName());}
