今天要做一个提示功能，所以看系统的Toast代码，自已改装了一下，下面这个就是精简版的Toast，使用方法和系统的方法一样，可以自己定义toast的layout。不多聊了，请看代码！！！
下面是自己写的自定义Toast的代码，
public class MyToast {
private final static String TAG = "MyToast";
public final static int HIDETOAST = 0;
public final static long SHORTTIME = 1000;
public final static long LONGTIME = 2000;
private final WindowManager.LayoutParams mParams = new WindowManager.LayoutParams();
WindowManager mWM;
private View mShowView;
private long mDuration;
private Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
int what = msg.what;
switch(what){
case HIDETOAST:
hide();
break;
default:
break;
}
}
};
public MyToast(Context context) {
mWM = (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);
mParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
mParams.width = WindowManager.LayoutParams.MATCH_PARENT;
mParams.format = PixelFormat.TRANSLUCENT;
mParams.windowAnimations = R.style.mytoast_anim;
mParams.type = WindowManager.LayoutParams.TYPE_TOAST;
mParams.flags = WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
| WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
| WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE;
mParams.x = 0;
int height = mWM.getDefaultDisplay().getHeight();
mParams.y = -height/2;
}
public static MyToast makeText(Context context, CharSequence text, long duration) {
MyToast result = new MyToast(context);
LayoutInflater inflate = (LayoutInflater)
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflate.inflate(R.layout.mytoast, null);
TextView tv = (TextView)v.findViewById(R.id.toast_msg);
tv.setText(text);
result.mShowView = v;
result.mDuration = duration;
return result;
}
public static MyToast makeText(Context context, int resId, long duration)
throws Resources.NotFoundException {
return makeText(context, context.getResources().getText(resId), duration);
}
public void show(){
if (mShowView.getParent() != null) {
Log.i( TAG, "mshowView:"+mShowView+" has parent.");
mWM.removeView(mShowView);
}
//ScaleAnimation animation = new ScaleAnimation(1.0f,1.0f,0.0f,1.0f);
//animation.setDuration(2000);
//mShowView.setAnimation(animation);
mWM.addView(mShowView, mParams);
mHandler.sendEmptyMessageDelayed(HIDETOAST, mDuration);
}
public void hide() {
if (mShowView != null) {
if (mShowView.getParent() != null) {
Log.v(TAG, "REMOVE! " + mShowView + " in " + this);
mWM.removeView(mShowView);
}
mShowView = null;
}
}
}自定义Toast，跟系统的一样好用，一样使用！！！
