package photoDoctor_Activity;
import photoDoctor.view.SettingItemView;
import com.sjm.photodoctor.R;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
public class SettingActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_setting);
initUpdate();
}
private void initUpdate() {
final SettingItemView siv_update = (SettingItemView) findViewById(R.id.siv_update);
siv_update.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
}
不加
siv_update.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
}
可以正常跳转到activity_setting界面，加上后程序就崩溃了，不知道什么原因，求解答。
