Android 下自定義Toast

自定義Toast中用到了windowManager這個類android

一下爲簡單介紹:數據庫

應用程序與窗口管理器的接口。WindowManager是Android中一個重要的服務。WindowManager Service是全局惟一的。它將用戶的操做,翻譯成指令,發送呈如今界面上的各個window。Activity會將頂級控件註冊到Window Manager中,當用戶觸碰屏幕或鍵盤時,Window Manager就會通知到,而當控件有一些請求產生,也會經由ViewParent送回到Window Manager中,從而完成整個通訊流程。app

整個Android的窗口機制就是基於一個叫作WindowManager,這個接口可添加View到屏幕,也可從屏幕移除View。它面向的對象一端是屏幕,另外一端就是View,經過WindowManager的addView()建立view,這樣產生的view根據WindowManager.LayoutParams屬性不一樣,效果也就不一樣了。好比建立系統頂級窗口,實現懸浮窗口效果。注意顯示出來就必定要銷燬掉(remove())。ide

3、獲取其實例的方法

一、WindowManager wm=(WindowManager) getSystemService(Context.WINDOW_SERVICE);佈局

二、WindowManager wm=(WindowManager) getWindowManger();this

下面直接貼代碼spa

/**
 * 自定義土司
 *
 * @param address
 */
public void myToast(String address) {
    /*繪製UI界面*/
    view = View.inflate(this, R.layout.address_show, null);
    TextView textview = (TextView) view.findViewById(R.id.tv_address);

    //"半透明","活力橙","衛士藍","金屬灰","蘋果綠"
    int[] ids = {R.mipmap.call_locate_white9, R.mipmap.call_locate_orange9, R.mipmap.call_locate_blue9
            , R.mipmap.call_locate_gray9, R.mipmap.call_locate_green9};

    /*得到用戶設置的風格,默認爲0半透明*/
    SharedPreferences sharedPreferences = getSharedPreferences("config", MODE_PRIVATE);

    view.setBackgroundResource(ids[sharedPreferences.getInt("which", 0)]);
    textview.setText(address);
    //窗體的參數就設置好了
    WindowManager.LayoutParams params = new WindowManager.LayoutParams();

    params.height = WindowManager.LayoutParams.WRAP_CONTENT;
    params.width = WindowManager.LayoutParams.WRAP_CONTENT;

    params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
            | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE
            | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON;
    params.format = PixelFormat.TRANSLUCENT;
    params.type = WindowManager.LayoutParams.TYPE_TOAST;
    windowManager.addView(view, params);

}
Toast佈局文件以下
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="center_vertical"
     >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@android:drawable/ic_menu_call" />

    <TextView
        android:textColor="#000000"
        android:id="@+id/tv_address"
        android:textSize="22sp"
        android:text="號碼歸屬地"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>
