PopupWindow做彈框

項目中常見的一個控件popupWindow,使用起來非常方便,可以隨心所欲的打進去一個View,就能達我們的目的;
這裏我基本是把項目中寫的代碼拷貝過來了,主要是彈出的一個自定的廣告popupWindow;

效果圖:

1.MainActivity.java

public class MainActivity extends AppCompatActivity {
    PopupWindow popupWindow;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button button = (Button) findViewById(R.id.popupWindow);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Log.i("diajij", "djoiajish");
                //直接自定義一個view然後打進去就ok了  我這裏演示一個廣告的popupWindow
                View itemView = View.inflate(MainActivity.this, R.layout.local_guanggao_detail_item, null);
                //測試 :自定義的view裏面只有一個TextView
                //TextView name = (TextView) itemView.findViewById(R.id.text_name);
                //name.setText("許可");
                TextView localDetailTvCityName = (TextView) itemView.findViewById(R.id.local_detail_tv_city_name);
                ImageView localDetailIvShiMing = (ImageView) itemView.findViewById(R.id.local_detail_iv_shiming);
                TextView localDetailTvShiMing = (TextView) itemView.findViewById(R.id.local_detail_tv_shiming);
                ImageView localDetailIvGuanFang = (ImageView) itemView.findViewById(R.id.local_detail_iv_guanfang);
                TextView localDetailTvGuanFang = (TextView) itemView.findViewById(R.id.local_detail_tv_guanfang);
                TextView localDetailTvCityPartner = (TextView) itemView.findViewById(R.id.local_detail_tv_city_partner);
                TextView localDetailTvContain = (TextView) itemView.findViewById(R.id.local_item_detail_tv_contain);
                TextView localDetailTvName = (TextView) itemView.findViewById(R.id.local_detail_tv_name);

                ImageView localDetailPhoneTb = (ImageView) itemView.findViewById(R.id.local_detail_phone_tb);
                TextView localDetailPhone = (TextView) itemView.findViewById(R.id.local_detail_phone);
                ImageView localDetailWeixinTb = (ImageView) itemView.findViewById(R.id.local_detail_weixin_tb);
                final TextView localDetailWeixin = (TextView) itemView.findViewById(R.id.local_detail_weixin);

                //右上角的叉叉圖片
                ImageView localDetailClose = (ImageView) itemView.findViewById(R.id.local_detail_close);
                localDetailClose.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        if (popupWindow != null) {
                            popupWindow.dismiss();
                        }
                    }
                });

                //城市名
                localDetailTvCityName.setText("中國");
                localDetailTvCityPartner.setText("城市合夥人");
                //頭像
                //MyApplication.imageLoader.displayImage(partnersBeen.get(i).headImg, localDetailCivHead, MyApplication.getAvatorOptions());

                //實名認證
                localDetailIvShiMing.setVisibility(View.VISIBLE);
                localDetailTvShiMing.setText("實名認證");

                //官方授權
                localDetailIvGuanFang.setVisibility(View.VISIBLE);
                localDetailTvGuanFang.setText("官方授權");

                //內容
                localDetailTvContain.setText("我是廣告內容,我是廣告內容,我是廣告內容,我是廣告內容,我是廣告內容,我是廣告內容");

                //負責人
                localDetailTvName.setText("負責人：許可");

                // 電話
                localDetailPhoneTb.setVisibility(View.VISIBLE);
                localDetailPhone.setText("888888888");
                localDetailPhone.setOnLongClickListener(new View.OnLongClickListener() {
                    @Override
                    public boolean onLongClick(View view) {
                        ClipboardManager cm = (ClipboardManager) getApplicationContext().getSystemService(Context.CLIPBOARD_SERVICE);
                        // 將文本內容放到系統剪貼板裏。
                        cm.setText(localDetailWeixin.getText());
                        Toast.makeText(getApplicationContext(), "手機號已經複製到剪切板了", Toast.LENGTH_SHORT).show();
                        return true;
                    }
                });

                //微信
                localDetailWeixinTb.setVisibility(View.VISIBLE);
                localDetailWeixin.setText("888888888");
                localDetailWeixin.setOnLongClickListener(new View.OnLongClickListener() {
                    @Override
                    public boolean onLongClick(View v) {
                        ClipboardManager cm = (ClipboardManager) getApplicationContext().getSystemService(Context.CLIPBOARD_SERVICE);
                        // 將文本內容放到系統剪貼板裏。
                        cm.setText(localDetailWeixin.getText());
                        Toast.makeText(getApplicationContext(), "微信已經複製到剪切板了", Toast.LENGTH_SHORT).show();
                        return true;
                    }
                });

                //創建popupWindow,第一個參數是自定義的view,第二個參數分別是popupWindow的寬和高(第四個參數是聚集(true/false),下面手動設置了)
                popupWindow = new PopupWindow(itemView, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

                //觸摸點擊事件
                popupWindow.setTouchable(true);
                //聚集
                popupWindow.setFocusable(true);
                //設置允許在外點擊消失
                popupWindow.setOutsideTouchable(true);
                //點擊返回鍵popupwindown消失
                popupWindow.setBackgroundDrawable(new BitmapDrawable());
                //背景變暗
                WindowManager.LayoutParams params = MainActivity.this.getWindow().getAttributes();
                params.alpha = 0.5f;
                MainActivity.this.getWindow().setAttributes(params);
                popupWindow.setTouchInterceptor(new View.OnTouchListener() {
                    @Override
                    public boolean onTouch(View v, MotionEvent event) {
                        return false;
                    }
                });

                //監聽如果popupWindown消失之後背景變亮
                popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
                    @Override
                    public void onDismiss() {
                        WindowManager.LayoutParams params = MainActivity.this.getWindow()
                                .getAttributes();
                        params.alpha = 1f;
                        MainActivity.this.getWindow().setAttributes(params);
                    }
                });
                popupWindow.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#00ffffff")));
                popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
            }
        });
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        popupWindow.dismiss();
    }
}

控件比較多,本來還有一個自定義的頭像在左上角的,由於文件比較多,這裏就把左上角的自定義圓形頭像給去掉了,主要是學習popupWindow的功能.
需要注意的是:注意什麼時候dismiss()掉popupWIndow;
