【问题描述】:
我一直在尝试动态添加TextInputLayout。每当点击RadioButton 时,TextInputLayout 就会添加到LinearLayout 下。
但在这一切之后,我得到了一个例外——
java.lang.IllegalArgumentException:您需要将 Theme.AppCompat 主题(或后代)与设计库一起使用。
虽然应用程序没有崩溃,但该错误点以下的代码没有被执行。
我已经搜索了StackOverflow和其他网站,寻找解决方案,但无论那里提到的似乎我已经做到了。
这是我迄今为止尝试过的——
MainActivity:
@Override
TextInputLayout textInputLayout3;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//some code here
ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.WRAP_CONTENT);
try{
textInputLayout3 = new TextInputLayout(getApplicationContext());
textInputLayout3.setLayoutParams(layoutParams);
editText3 = new EditText(getApplicationContext());
editText3.setLayoutParams(layoutParams);
editText3.setHint("Search by Rating:");
textInputLayout3.addView(editText3);
radio3 = (RadioButton)findViewById(R.id.radio3);
Layout3 = (LinearLayout) findViewById(R.id.ll3);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if(checkedId == radio1.getId()) {
//again some code here
}
if(checkedId == radio2.getId()) {
//again some code here
}
if(checkedId == radio3.getId()) {
Layout3.addView(textInputLayout3);
}
}
});
}
catch(Exception e)
{
e.printStackTrace();
}
}
Application(app) build.gradle:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
compile 'com.android.support:recyclerview-v7:23.1.1'
}
清单 XML:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="saubhattacharya.learningappone.com">
<uses-permission android:name="android.permission.INTERNET" />

<application
android:allowBackup="true"

android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
样式 XML:
<resources>
<!-- Base application theme. -->
<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>
<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
看起来一切就绪,但我仍然面临这个奇怪的问题。
谁能帮我找出问题所在?提前致谢!
