我在我的代码中使用了对话框主题，但模拟器显示的是不幸的对话框已停止的消息。 我的AVD仿真器细节如下： Nexus 7 API 19 皮肤：HVGA
这是我的manifest.xml文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

这是我的main.java文件
package com.example.dialog;

public class MainActivity extends ActionBarActivity {

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

@Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}`
Here is my log when I launched my app

这是我的Styles.xml文件
<resources>
<!--
Base application theme, dependent on API level. This theme is replaced
by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
<!--
Theme customizations available in newer API levels can go in
res/values-vXX/styles.xml, while customizations related to
backward-compatibility can go here.
-->
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
</resources>
答案 0 :(得分：0)
您继承ActionBarActivity（正如日志所示）要求您使用AppCompat主题。
将styles.xml设置为：
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
</style>
修改
此外，在您的清单中删除此内容：
android:theme="@android:style/Theme.Dialog">
否则使用不同的活动类，例如Activity。
