活动不断崩溃
我用一个Activity创建了一个应用程序但是当我尝试运行它时（我通过USB连接了我的OPT）它一直在崩溃。我希望至少我能看到第一个屏幕，但我觉得我做错了什么。这是我到目前为止所做的：
MainActivity.java -
package com.excalibur.present;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
activity_main.xml中
这就是它的样子

答案 0 :(得分：-1)
尝试： AppCompatActivity的布局主题也需要是AppCompat主题。
但请粘贴清单和布局文件。
