Android 下自定义Toast

摘要: Toast

自定义Toast中用到了windowManager这个类

一下为简单介绍：

应用程序与窗口管理器的接口。WindowManager是Android中一个重要的服务。WindowManager Service是全局唯一的。它将用户的操作，翻译成指令，发送呈现在界面上的各个window。Activity会将顶级控件注册到Window Manager中，当用户触碰屏幕或键盘时，Window Manager就会通知到，而当控件有一些请求产生，也会经由ViewParent送回到Window Manager中，从而完成整个通信流程。

整个Android的窗口机制就是基于一个叫做WindowManager，这个接口可添加View到屏幕，也可从屏幕移除View。它面向的对象一端是屏幕，另一端就是View，通过WindowManager的addView()创建view，这样产生的view根据WindowManager.LayoutParams属性不同，效果也就不同了。比如创建系统顶级窗口，实现悬浮窗口效果。注意显示出来就一定要销毁掉(remove())。

三、获取其实例的方法
1、WindowManager wm=(WindowManager) getSystemService(Context.WINDOW_SERVICE);

2、WindowManager wm=(WindowManager) getWindowManger();

下面直接贴代码

/**
* 自定义土司
*
* @param address
*/
public void myToast(String address) {
/*绘制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","卫士蓝","金属灰","苹果绿"
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};

/*获得用户设置的风格，默认为0半透明*/
SharedPreferences sharedPreferences = getSharedPreferences("config", MODE_PRIVATE);

view.setBackgroundResource(ids[sharedPreferences.getInt("which", 0)]);
textview.setText(address);
//窗体的参数就设置好了
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布局文件如下

<?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:
3ff0
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="号码归属地"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

</LinearLayout>

调用代码如下

}

}

}
}

}

@Override
