改变吐司的颜色，位置和背景颜色的方法是：

    Toast toast=Toast.makeText(getApplicationContext(),"This is advanced toast",Toast.LENGTH_LONG);
    toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT,0,0);
    View view=toast.getView();
    TextView  view1=(TextView)view.findViewById(android.R.id.message);
    view1.setTextColor(Color.YELLOW);
    view.setBackgroundResource(R.color.colorPrimary);
    toast.show();

创建自定义Toast布局，例如correct_toast.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/toast_layout_root"
          android:orientation="horizontal"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:padding="8dp"
          android:background="#DAAA">
    <TextView android:id="@+id/text"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:textColor="#FFF"
              />
</LinearLayout>

然后在java代码中，用这个视图构造toast：

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.correct_toast,
                           (ViewGroup) findViewById(R.id.toast_layout_root));

TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("This is a custom toast");

Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();

这样，您就可以更改背景颜色和/或更改文本颜色。
