Android开发笔记

1.使用Glide加载图片

        Glide.with(mContext).load(bean.getLogo())
                .diskCacheStrategy(DiskCacheStrategy.ALL)
                .placeholder(R.color.white)
//                            .animate(R.anim.zoom_in)
                .crossFade()
                .error(R.drawable.default_load)
                .into(holder.nimg_icon);

if (newState == RecyclerView.SCROLL_STATE_IDLE) {
                    Glide.with(GoldCoinActivity.this).resumeRequests();
                } else {
                    Glide.with(GoldCoinActivity.this).pauseRequests();
                }

Glide.with(mContext).load(item.getUserAvatar())
     .crossFade().into((ImageView) helper.getView(R.id.iv));  

2.TextView设置Html标签文本

tv_ver.setText(Html.fromHtml("￥ "));

3.ListView的条目加载动画

//动画加载
    private void setAnimation(View viewToAnimate, int position) {
        if (position > lastPosition) {
            Animation animation = AnimationUtils.loadAnimation(viewToAnimate.getContext(), R
                    .anim.item_bottom_in);
            viewToAnimate.startAnimation(animation);
            lastPosition = position;
        }
    }

4.PopuWindow重写返回键

contentview.setOnKeyListener(new View.OnKeyListener() {
            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                if (keyCode == KeyEvent.KEYCODE_BACK) {
                    popupWindow.dismiss();
                    return true;
                }
                return false;
            }
        });

5.view需要响应模拟点击的时候调用performClick()方法即可

6.等待子线程结束

try {
                    thread.join();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }

7.动态添加TextView

for (int i = 0; i < contentBean.getPersonal_mark().size(); i++) {
                View convertView = LayoutInflater.from(this).inflate(
                        R.layout.item_guide_detail_tag, null);
                TextView textView = (TextView) convertView.findViewById(R.id.tv_tag);
                textView.setText(contentBean.getPersonal_mark().get(i));
                ll_like.addView(convertView);
            }

8.复写键盘搜索

 cet_content.setOnEditorActionListener(mOnEditorActionListener);
/**
     * 修改的键盘搜索按钮点击事件
     */
    private TextView.OnEditorActionListener mOnEditorActionListener=new TextView.OnEditorActionListener() {

        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_SEARCH) {
                ((InputMethodManager) cet_content.getContext().getSystemService(Context.INPUT_METHOD_SERVICE))
                        .hideSoftInputFromWindow(
                                BrandShopsHotSearchActivity.this.getCurrentFocus().getWindowToken(),
                                InputMethodManager.HIDE_NOT_ALWAYS);
                if (TextUtils.isEmpty(cet_content.getText().toString().trim())) {
                    ToastUtil.show(BrandShopsHotSearchActivity.this, "搜索内容不能为空!");
                    return true;
                }
                String key = cet_content.getText().toString().trim();
                BrandShopsActivity.activities.get(0).finish();
                BrandShopsActivity.startAction(BrandShopsHotSearchActivity.this, key);
                cet_content.setText("");
                finish();
                return true;
            }
            return false;
        }
    };

9.给TextView动态设置图片

Drawable drawable = getResources().getDrawable(R.mipmap.icon_arrow_down_more);
                    drawable.setBounds(0, 0, drawable.getMinimumWidth(), drawable.getMinimumHeight());
                    tv_hotscenic.setCompoundDrawables(null, null, drawable, null);

10.利用广播机制管理Activity

    /**
     * 退出广播对应的ACTION
     */
    public final static String INIENT_FINISH = "com.allfinish.method.finish";


    /**
     * 初始化退出广播
     */
    public void initFinishReceiver() {
        IntentFilter filter = new IntentFilter();
        filter.addAction(INIENT_FINISH);
        registerReceiver(mFinishReceiver, filter);
    }

    /**
     * 监听是否退出的广播
     */
    public BroadcastReceiver mFinishReceiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            if (INIENT_FINISH.equals(intent.getAction())) {
                finish();
            }
        }
    };





    @Override
    protected void onDestroy() {
        // TODO Auto-generated method stub
        unregisterReceiver(mFinishReceiver);
        super.onDestroy();
    }


    /**
     * 发送广播退出多个Activity
     */
    private void sendFinish() {
        getApplicationContext().sendBroadcast(new Intent(INIENT_FINISH));
    }

11.刷新adapter指定item

    public void updataView(int index, Object obj, ListView listView) {
        TourGuideOfCircleListBean.ContentBean contentBean = (TourGuideOfCircleListBean.ContentBean) obj;
        int visibleFirstPosi = listView.getFirstVisiblePosition();
        int visibleLastPosi = listView.getLastVisiblePosition();
        if (index >= visibleFirstPosi && index <= visibleLastPosi) {
            View view = listView.getChildAt(index - visibleFirstPosi);
            ViewHolder holder = (ViewHolder) view.getTag();

            holder.tv_parise_num.setText(contentBean.getPraise());
            list.set(index, obj);
        } else {
            list.set(index, obj);
        }
    }

12.头布局

View headerView = getLayoutInflater().inflate(R.layout.headview_guide_business, null);
