我想知道是否有办法在 a 中显示所有文本Toast
以使其居中。例如,我有一个Toast
里面有 2 行文本。出于纯粹的审美原因,我希望文本居中对齐而不是左对齐。我浏览了文档,找不到任何关于它的信息。有没有一种我错过的简单方法可以做到这一点?

改编自另一个答案:
Toast toast = Toast.makeText(this, "Centered\nmessage", Toast.LENGTH_SHORT);
TextView v = (TextView) toast.getView().findViewById(android.R.id.message);
if( v != null) v.setGravity(Gravity.CENTER);
toast.show();

Toast 建立在 TextView 之上,并且它的默认重力是左对齐的。因此,您需要像这样创建自己的 TextView :
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical|center_horizontal"
android:text="all the text you want"
/>
然后你将 TextView 分配给 Toast,如下所示:
Toast t = new Toast(yourContext);
t.setView(yourNewTextView);

没有黑客:
String text = "Some text";
Spannable centeredText = new SpannableString(text);
centeredText.setSpan(
new AlignmentSpan.Standard(Layout.Alignment.ALIGN_CENTER),
0, text.length() - 1,
Spannable.SPAN_INCLUSIVE_INCLUSIVE
);
Toast.makeText(getActivity(), centeredText, Toast.LENGTH_LONG).show();
除了中心之外,还有其他对齐方式。

这是肮脏的黑客,但是
((TextView)((LinearLayout)toast.getView()).getChildAt(0))
.setGravity(Gravity.CENTER_HORIZONTAL);

使用 Toast 的setView(view)
功能来提供一个View
with Gravity.CENTER
。

并不是说这findViewById(android.R.id.message)
是错误的,但以防万一(未来?)实现差异我自己使用了一些不同的方法:
void centerText(View view) {
if( view instanceof TextView){
((TextView) view).setGravity(Gravity.CENTER);
}else if( view instanceof ViewGroup){
ViewGroup group = (ViewGroup) view;
int n = group.getChildCount();
for( int i = 0; i<n; i++ ){
centerText(group.getChildAt(i));
}
}
}
接着:
Toast t = Toast.makeText(context, msg,Toast.LENGTH_SHORT);
centerText(t.getView());
t.show();

在科特林:
fun makeToast(context: Context, resId: Int) {
val toast = Toast.makeText(context, resId, Toast.LENGTH_SHORT)
val view = toast.view.findViewById<TextView>(android.R.id.message)
view?.let {
view.gravity = Gravity.CENTER
}
toast.show()
}

It is work for me:
Toast toast = Toast.makeText(context, message, Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER| Gravity.BOTTOM, 0, 20);
toast.show();

这种变化是LinearLayout
在您的布局 xml 中使用的 :)
Toast SampleToast = Toast.makeText(this, "This is the example of centered text.\nIt is multiline text.", Toast.LENGTH_SHORT);
LinearLayout OurLayout = (LinearLayout) SampleToast.getView();
if (OurLayout.getChildCount() > 0) {
TextView SampleView = (TextView) OurLayout.getChildAt(0);
SampleView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
}
SampleToast.show();

Toast t=Toast.makeText(getApplicationContext(),"Text",Toast.LENGTH_LONG);
t.setText("Password Does't match...");
t.setGravity(0, 0, 0);
t.show();
吐司的简单代码最重要
