Question

我有一个Snackbar，如果在向服务器请求数据后没有找到任何度假村，则应显示该Snackbar。每次需要显示java.lang.RuntimeException: An error occurred while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:309) at

ListActivity

我当前的课程延伸ActionBar并正在实施pDialog.dismiss(); Snackbar.make(parentLayout, "No resorts found", Snackbar.LENGTH_INDEFINITE) .setAction("CLOSE", new View.OnClickListener() { @Override public void onClick(View view) { Bundle data = getIntent().getExtras(); Intent i = new Intent(Result.this, OptionList.class); i.putExtras(data); setResult(RESULT_OK, getIntent()); finish(); } }) .setActionTextColor(getResources().getColor(android.R.color.holo_blue_dark )) .show();。

如果我用Toast替换Snackbar消息，它可以正常工作。

活动的XML：

parentLayout = findViewById(android.R.id.content);

父布局代码：

Snackbar

Theme.Holo.Light.ActionBar在添加操作栏之前完美运行。

对于此活动，我使用<activity android:name=".Result" android:launchMode="singleTop" android:theme="@android:style/Theme.Holo.Light.DarkActionBar" android:parentActivityName="com.tripoffbeat.OptionList"/> Android清单：

styles.xml

在我的<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">我的主题是// You can use some library like "Lodash" to use such functions. // returns random integer in span <min:max> function randomInteger(min = 1, max = 100){ // in case that there are wrong values if(min >= max){throw new Error(`Hey i cant get random integer in range min:${min} to max:${max}`)} return Math.round((Math.random() * (max-min))+min) } // buttons var number1GeneratorButton = document.getElementById('number1-generator'), number2GeneratorButton = document.getElementById('number2-generator'), calculateSumButton = document.getElementById('sum-button'), resetPageButton = document.getElementById('reset-page'); // outputs var number1Output = document.getElementById('number1'), number2Output = document.getElementById('number2'), sumOutput = document.getElementById('sum'); // add event listeners to the buttons number1GeneratorButton.addEventListener('click', function(){ number1Output.innerHTML = randomInteger(); }) number2GeneratorButton.addEventListener('click', function(){ number2Output.innerHTML = randomInteger(); }) calculateSumButton.addEventListener('click', function(){ var sum = parseInt(number1Output.innerHTML) + parseInt(number2Output.innerHTML); sumOutput.innerHTML = sum; }) resetPageButton.addEventListener('click', reloadWindow) function reloadWindow() { window.location.reload(true); } // function addTextNode2(simple3) { // text3 = text2 + text1 // var newtext1 = document.createTextNode(text3), // p3 = document.getElementById("p3"); // p3.appendChild(newtext1); // } // function addTextNode4() { // if (text1 > text2){ // text3 = text1 - text2; // var newtext4 = document.createTextNode(text3), // p3 = document.getElementById("p3");} // else if(text2 > text1){ // text3 = text2 - text1;");} // var newtext4 = document.createTextNode(text3), // p3 = document.getElementById("p3 // p3.appendChild(newtext4); // } // function test(sampleplace1){ // if(text1 > text2){ // q = text1 - text2; // var storm = document.createTextNode(q).value, // p1 = document.getElementById("p1");} // else if(text2 > text1){ // z = text2 - text1; // var storm = document.createTextNode(z).value, // p1 = document.getElementById("p1"); // } // p1.appendChild(storm); // }。

Answer 1

当Snackbar从its content layout充气时，cannot inflate a Button会从该布局中消失{{3}}，因为它无法从当前上下文的主题中找到?attr/colorAccent。这种情况正在发生，因为您的活动主题不是AppCompat主题的后代。

所以，而不是：

android:theme="@android:style/Theme.Holo.Light.DarkActionBar"

应用一些 appcompatish 主题。假设应用程序的主题为Theme.AppCompat.Light.DarkActionBar。

，从清单中删除该行将解决您的错误

尝试使用Snackbar时出现InflateException
