自定义Toast，防止层叠显示问题，和自定义Toast样式

做Android开的人都应该知道，Android原生Toast在短时间多次show的情况下会出现层叠和重复显示问题，即使APP整个进程被杀了，Toast还是会一直显示直至你最后一个Toast显示完，本文就是针对此问题给出了一个个人的解决办法，先看代码：

 public static void showShort(Context mcContext, String msg) {
	if (null == mToast) {
	    mToast = Toast.makeText(mcContext, msg, Toast.LENGTH_SHORT);
	    // mToast.setGravity(Gravity.BOTTOM, 0, 350);
	} else {
	    mToast.setText(msg);
	}
	mToast.show();
    }

 

 

 

原理就是利用单例模式，不让Toast重复new 对象，这样不仅省资源，而且也避免了重复弹出的问题

 

1.默认效果:

代码:

Toast.makeText(getApplicationContext(), "默认Toast样式",
     Toast.LENGTH_SHORT).show();

 

 

 

 

 

2.自定义显示位置效果:

代码:

toast = Toast.makeText(getApplicationContext(),
     "自定义位置Toast", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.CENTER, 0, 0);
   toast.show();

 

 

 

 

 

 3.带图片效果:

代码

toast = Toast.makeText(getApplicationContext(),
     "带图片的Toast", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.CENTER, 0, 0);
   LinearLayout toastView = (LinearLayout) toast.getView();
   ImageView imageCodeProject = new ImageView(getApplicationContext());
   imageCodeProject.setImageResource(R.drawable.icon);
   toastView.addView(imageCodeProject, 0);
   toast.show();

 

 

 

 

 

 

 

4.完全自定义效果:

代码

LayoutInflater inflater = getLayoutInflater();
   View layout = inflater.inflate(R.layout.custom,
     (ViewGroup) findViewById(R.id.llToast));
   ImageView image = (ImageView) layout
     .findViewById(R.id.tvImageToast);
   image.setImageResource(R.drawable.icon);
   TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);
   title.setText("Attention");
   TextView text = (TextView) layout.findViewById(R.id.tvTextToast);
   text.setText("完全自定义Toast");
   toast = new Toast(getApplicationContext());
   toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);
   toast.setDuration(Toast.LENGTH_LONG);
   toast.setView(layout);
   toast.show();

 

 

 

 

 

 

 

5.其他线程:

 代码:

new Thread(new Runnable() {
    public void run() {
     showToast();
    }
   }).start();
