java 如何在android中为Toast自定义背景、背景颜色和文本颜色

How to customize background, background color and text color for Toast in android

提问by Aoyama Nanami

I want to customize my toast without creating a custom layout by modifying the default Toast. I want red color for toast's background, and white color for toast's text color and I want to make my toast's background bigger that default toast. when I run my application, there's nothing change from my toast, it still show in default toast.

我想通过修改默认 Toast 来自定义我的 Toast，而不创建自定义布局。我想要吐司背景的红色，吐司文本颜色的白色，我想让我的吐司背景比默认吐司大。当我运行我的应用程序时，我的 toast 没有任何变化，它仍然显示在默认的 toast 中。

This is how I customize my toast:

这是我自定义吐司的方式：

if (seriesSelection == null) {
    Toast toast = Toast.makeText(getApplicationContext(), "tidak ada chart yang dipilih", Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.CENTER, 50, 50);
    toast.getView().setPadding(10, 10, 10, 10);
    toast.getView().setBackgroundColor(Color.RED);
    TextView text = (TextView) toast.getView().findViewById(android.R.id.message);
    text.setTextColor(Color.WHITE);
    text.setTextSize(14);
} else {
    Toast toast=  Toast.makeText(
            getApplicationContext(),
            "Nilai " + listData.get(seriesSelection.getPointIndex()).getInuNilai()+
            "  tanggal " + listData.get(seriesSelection.getPointIndex()).getTanggal(), 
            Toast.LENGTH_SHORT); 
    toast.setGravity(Gravity.CENTER, 50, 50);
    toast.getView().setPadding(10, 10, 10, 10);
    toast.getView().setBackgroundColor(Color.RED);
    text.setTextColor(Color.WHITE);
    text.setTextSize(14);
    toast.show();
}

You can have a custom view inflate a custom view and use toast.setView(layout).

您可以让自定义视图膨胀自定义视图并使用toast.setView(layout).

Example:

例子：

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_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();

And your xml

还有你的 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"
              >
    <ImageView android:src="@drawable/droid"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:layout_marginRight="8dp"
               />
    <TextView android:id="@+id/text"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:textColor="#FFF"
              />
</LinearLayout>

Ran your if and else part of the code (separately) it shows toast with red background and white text color. I don't see any problem. But if you need to customize you can use a custom layout and inflate the layout and set the view to the toast.

运行 if 和 else 部分代码（单独），它显示带有红色背景和白色文本颜色的吐司。我看不出有什么问题。但是如果您需要自定义，您可以使用自定义布局并扩展布局并将视图设置为 toast。

Edit:

编辑：

Your textview

你的文本视图

  TextView text = (TextView) toast.getView().findViewById(android.R.id.message);

is initialized in the if part and in else part textview is not initialized.

在 if 部分初始化，在 else 部分 textview 未初始化。

Initialize textview outside if and else code.

在 if 和 else 代码之外初始化 textview。

Toast has a setView()method.

吐司是有setView()方法的。

You can customize a Toast to show any view.

您可以自定义 Toast 以显示任何视图。

I'd say instead of trying to edit the view inside the Toast, you just create a View and pop it in yourself.

我想说，与其尝试编辑 Toast 中的视图，不如创建一个视图并将其弹出。

    View view = toast.getView();
    view.setPadding(20, 20, 20, 20);
    view.setBackgroundResource(R.color.GREEN);
    view.setTextColor(Color.RED);
