textview 通過SpannableString 打開activity

public class MainActivity extends Activity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView textView = (TextView) this.findViewById(R.id.textView);
        TextView textView2 = (TextView) this.findViewById(R.id.textView2);
        String text1 = "顯示act1";
        String text2 = "顯示act2";
        //表示字符串添加事件吧
        SpannableString spannableString = new SpannableString(text1);
        SpannableString spannableString2 = new SpannableString(text2);
        //從0.text的長度設置click 
        spannableString.setSpan(new ClickableSpan() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(MainActivity.this,Activity1.class);
startActivity(intent);

}
}, 0, text1.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        spannableString2.setSpan(new ClickableSpan() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(MainActivity.this,Activity2.class);
startActivity(intent);
}
}, 0, text2.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
        textView.setText(spannableString);
        textView2.setText(spannableString2);
        textView.setMovementMethod(LinkMovementMethod.getInstance());
        textView2.setMovementMethod(LinkMovementMethod.getInstance());
        
    }
