startActivity(intent);失败：进程意外停止,该怎么解决

startActivity(intent);失败：进程意外停止
Hi，开始写android例子，测试在两个activity之间，用intent跳转的时候，发现startActivity(intent)这个句子总是失败。
想实现从MainActivity带参数跳转到SubActivity，配置如下，请各位大虾点一下啊：
MainActivity.java

public class MainActivity extends Activity implements OnClickListener {
	Button submit;
	TextView view1;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		submit = (Button) this.findViewById(R.id.submit);
		view1 = (TextView) this.findViewById(R.id.view1);
		submit.setOnClickListener(this);
	}
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}
	@Override
	public void onClick(View v) {
		Intent intent = new Intent();
		intent.setClass(MainActivity.this, SubActivity.class);// 从哪里来，到哪里去
		intent.putExtra("view1", view1.getText());
		intent.putExtra("view11", view1.getText() + "1123");
                startActivity(intent);//注释掉这里，不会报错。所以应该是这里出错了
	}
}
