我试图将TextInputLayout与Theme.material一起使用,代码看起来像....
activity_mail.xml
<?xml version="1.0" encoding="utf-8"?>

MainActivity看起来像这样..
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
当我尝试执行此
时Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

这是我观察到的控制台。
任何人都可以帮我找到错误的地方。

更改以下文件
<强> style.xml 强>
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
</resources>
<强> colors.xml 强>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#1a237e</color>
<color name="transparent">@android:color/transparent</color>
<color name="colorAccent">#FF4081</color>
<color name="windowBackground">#313131</color>
</resources>
您可以根据需要更改颜色。
<强>的AndroidManifest.xml 强>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
//your activities
</application>
希望这会有所帮助...

TextInputLayout是support
库的一部分(正如您所看到的那样,它是设计库的一部分)。支持库中的所有支持组件都与其他支持组件(如主题)互补。在这种情况下,您需要使用Theme.AppCompat
。但不用担心,所有compat ui元素都是为了支持旧的Android版本而构建的,但如果您使用app compat主题,它会自动使用Material主题实现在您的应用中生成UI。
总结一下:你必须Theme.AppCompat
,但它等于Android OS中的Material Theme&gt; = 5.0
只需使用:
<style name="AppTheme" parent="Theme.AppCompat">
而不是标准材料。
