添加TextInputLayout会动态抛出异常 [英] Adding TextInputLayout dynamically throws Exception

问题描述

我一直在尝试动态添加 TextInputLayout 。只要点击 RadioButton ，就会在 LinearLayout TextInputLayout c $ c>。

I have been trying to add a TextInputLayout dynamically. Whenever a RadioButton will be clicked, a TextInputLayout will be added under a LinearLayout.

但在这之后，我得到一个例外 -

But after all this, I am getting an exception --

java.lang.IllegalArgumentException：您需要将Theme.AppCompat主题（或后代）与设计库一起使用。

java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library.

虽然应用程序没有崩溃，但是这个错误点之下的代码没有被执行。

Although the app is not crashing, but the code below the point of this error is not getting executed.

我已遍布 StackOverflow 和其他网站一样，寻找解决方案，但无论提到什么，看起来我已经做过了。

I have searched all over StackOverflow and other websites as well, looking for a solution, but whatever was mentioned there looks like I already have done it.

这就是我所拥有的到目前为止尝试了 -

Here goes what I have tried so far --

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();
    }
}

应用程序（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" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application
    android:allowBackup="true"
    android:icon="@drawable/learningapponeicon"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        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>

看起来一切都已到位，但我仍然面临着这个奇怪的问题。

Looks like everything is in place, but I am still facing this weird issue.

任何人都可以帮我找出问题所在吗？在此先感谢！

Can anybody please help me to identify what went wrong? Thanks in advance!

推荐答案

不要使用您的应用程序上下文来创建样式化视图，因为样式不适用于此上下文。

Don't use your app context to create styled views because styling doesn't work with this context.

new TextInputLayout（getApplicationContext（））;

new TextInputLayout(getApplicationContext());

你应该使用你的活动背景

you should use your activity context

new TextInputLayout(this);
