颜色自定义

getResource().getColor( colorId); 方法废弃
ContextCompat.getColor(context, colorId); 替代方法

Toast toast = Toast.makeText(context, text, duration);TextView textView = (TextView) toast.getView().findViewById(android.R.id.message);textView.setTextColor(Color.YELLOW); // 字体颜色toast.getView().setBackgroundColor(ContextCompat.getColor(context, R.color.indigo)); // 背景颜色

视图自定义

1 toast_text.xml

<?xml version="1.0" encoding="utf-8"?>  <TextView          xmlns:android="http://schemas.android.com/apk/res/android"        android:id="@+id/txtMessage"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:drawableStart="@drawable/ic_report_problem"        android:drawablePadding="8dp"        android:paddingTop="8dp"        android:paddingBottom="8dp"        android:paddingLeft="16dp"        android:paddingRight="16dp"        android:gravity="center"        android:textColor="@android:color/white"        android:textSize="16dp"        android:text="No connection."        android:background="@color/indigo"/>

2 setView()

Toast toast = new Toast(getApplicationContext());View view = getLayoutInflater().inflate(R.layout.toast_view, null);toast.setView(view); // 设置TextViewtoast.setDuration(Toast.LENGTH_LONG); // 设置[视图显示]时长int margin = getResources().getDimensionPixelSize(R.dimen.toast_vertical_margin);toast.setGravity(Gravity.BOTTOM | Gravity.CENTER_VERTICAL, 0, margin);toast.show(); // 显示 吐司

方法解析 [简单]

R.layout.transient_notification
这个xml文件，就是toast视图文件

getView()
setView()
操作的都是这个xml文件

    public static Toast makeText(Context context, CharSequence text, @Duration int duration) {        Toast result = new Toast(context);        LayoutInflater inflate = (LayoutInflater)                context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);        View v = inflate.inflate(com.android.internal.R.layout.transient_notification, null);        TextView tv = (TextView)v.findViewById(com.android.internal.R.id.message);        tv.setText(text);        result.mNextView = v;        result.mDuration = duration;        return result;    }

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:background="?android:attr/toastFrameBackground">    <TextView        android:id="@android:id/message"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_weight="1"        android:layout_gravity="center_horizontal"        android:textAppearance="@style/TextAppearance.Toast"        android:textColor="@color/bright_foreground_dark"        android:shadowColor="#BB000000"        android:shadowRadius="2.75"        /></LinearLayout>
