FragMent-通过Arguments方法 跟activity通信

今天主要学习下通过Arguments，实现activity 给fragment传递数据。这个方法也是通过参数bundle来进行数据传输的

直接看如下代码

一，定义一个fragment，在oncreateView 中实现布局

public View onCreateView(LayoutInflater inflater,
                ViewGroup container,  Bundle savedInstanceState) {
            mView = inflater.inflate(R.layout.detail_dialog, container, false);
            if (mView != null) {
                mTitleView = (TextView) mView.findViewById(R.id.title);
                mTimeView = (TextView) mView.findViewById(R.id.time);
                mDurationView = (TextView) mView.findViewById(R.id.duration);
                mPathView = (TextView) mView.findViewById(R.id.path);
                mFileSizeView = (TextView) mView.findViewById(R.id.filesize);
                //通过getArguments获得bundle数据
                mTitleView.setText(getArguments().getString("mTitle",""));
                android.util.Log.e("zhangshuli", "+++++++"+getArguments().getString("mTitle",""));
                mPathView.setText(getArguments().getString("mData",""));
                mDurationView.setText(getArguments().getString("mDuration",""));
                 //   +MtkUtils.stringForTime(mHolder.mDuration));
                mTimeView.setText(getArguments().getString("mDateTaken",""));
                    //+MtkUtils.localTime(mHolder.mDateTaken));
                mFileSizeView.setText(getArguments().getString("mFileSize",""));
                //+Formatter.formatFileSize(mContext, mHolder.mFileSize));
                //  setButton(BTN_OK, mContext.getString(android.R.string.ok), this);
            } else {
                return super.onCreateView(inflater, container, savedInstanceState);
            }
    

activity 中实现引用

private void showDetail(final ViewHolder mHolder) {
                String mTitle =""+mHolder.mTitle;
                String mData=""+mHolder.mData;
                String mDuration =""+MtkUtils.stringForTime(mHolder.mDuration);
                String mDateTaken =""+MtkUtils.localTime(mHolder.mDateTaken);
                String mFileSize =""+Formatter.formatFileSize(this, mHolder.mFileSize);
                mFragment=new DetailFragment();
                mBundle =new Bundle();
                fmFragmentManager=getFragmentManager();
                mBundle.putString("mTitle", mTitle);
                mBundle.putString("mData", mData);
                mBundle.putString("mDuration", mDuration);
                mBundle.putString("mDateTaken", mDateTaken);
                mBundle.putString("mFileSize", mFileSize);
                android.util.Log.e("zhangshuli", "======"+mFileSize);
                //通过setArguments给fragment传递数据
                mFragment.setArguments(mBundle);
                fmFragmentManager.beginTransaction().replace(R.id.main,mFragment).commit();
    }
