当我添加一些东西时，DisplayActivity.java 的规范总是崩溃。无法弄清楚我做错了什么。这是我当前的代码。

"Root Granted", Toast.LENGTH_SHORT);

"Root Access Needed To Continue", Toast.LENGTH_LONG);
noRoot.show();
finish();
}
Resources res = getResources(); // used to get res drawings (i.e. display files)
TabHost tabHost = getTabHost(); // used to create TabHost located in main.xml
TabHost.TabSpec spec; //TabHost specifications which are the same in each view
Intent intent; //intent for each tab. *RESEARCH INTENT*
// New Class Added Caused FC. Was working. Spec no longer working again.
//____Display
intent = new Intent().setClass(this, DisplayActivity.class);
spec = tabHost.newTabSpec("display").setIndicator("Display",
res.getDrawable(R.drawable.ic_tab_display))
.setContent(intent); // create picture to be used for tab
tabHost.addTab(spec);
