android toast用法总结（一）

1，Toast简单用法：

//利用工厂方法构造一个简单的Toast,并链式结构的直接进行提示Toast.makeText(this, "这是一个Toast示",Toast.LENGTH_LONG).show();

2，Toast也是一个容器，可以包含各种View，承载着它们显示出来，

//初始化ToastToast toast = new Toast(this);//设置显示时间，可以选择Toast.LENGTH_LONG或者Toast.LENGTH_SHORTtoast.setDuration(Toast.LENGTH_LONG); //承载一个TextView，用来显示文字TextView tview = new TextView(this);//设置TextView的值tview.setText("这是一个Toast提示");//设置TextView的布局tview.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT));//Toast承载该viewtoast.setView(tview);//显示Toasttoast.show();

3，包含Layout，并显示：

Toast toast = new Toast(this);toast.setDuration(Toast.LENGTH_LONG);TextView tview = new TextView(this);ImageView iView = new ImageView(MainActivity.this);tview.setText("Toast提示");            iView.setImageResource(R.drawable.ic_launcher);//tview.setLayoutParams(new LayoutParams(//LinearLayout.LayoutParams.WRAP_CONTENT,//LinearLayout.LayoutParams.WRAP_CONTENT));// Toast承载该layoutLinearLayout layout = new LinearLayout(MainActivity.this);            layout.setOrientation(LinearLayout.VERTICAL);layout.addView(iView);layout.addView(tview);toast.setView(layout);toast.setGravity(Gravity.CENTER, 0, 0);// toast.setMargin(0f, 0.5f);toast.show();

Toast.setView源码：

 View mNextView;/**     * Set the view to show.     * @see #getView     */    public void setView(View view) {        mNextView = view;    }

4，获得toast的布局

Toast toast1=Toast.makeText(this, "显示带图片的toast", 3000); toast1.setGravity(Gravity.CENTER, 0, 0);  ImageView imageView= new ImageView(getApplicationContext()); imageView.setImageResource(R.drawable.ic_launcher); //获得toast的布局 LinearLayout toastView = (LinearLayout) toast1.getView(); toastView.setOrientation(LinearLayout.VERTICAL); //将ImageView在加入到此布局中的第一个位置 toastView.addView(imageView, 0); toast1.setView(toastView);toast1.show();

5，

Toast toast3 = Toast.makeText(this, "这是一个代图片的Toast!", Toast.LENGTH_LONG);ImageView imageView3 = new ImageView(this);            imageView3.setImageResource(R.drawable.ic_launcher);View toastView3 = toast3.getView();LinearLayout linearLayout3 = new LinearLayout(this);            linearLayout3.setOrientation(LinearLayout.VERTICAL);             // 将ImageView和ToastView合并到Layout中 linearLayout3.addView(imageView3);linearLayout3.addView(toastView3);// 替换掉原有的ToastView toast3.setView(linearLayout3);toast3.show();
