您好我正在开发一个Android应用程序,没什么好看的只是一些小的大学。在我使用R的地方,我收到最后一位的错误。示例R.id。 mediAware 任何帮助将不胜感激。
如果有帮助,这是我的代码:
package com.example.medicalapp;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
import android.widget.TextView;
import com.example.medicalapp.R;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ImageView img1 = (ImageView) findViewById(R.id.mediAware);
ImageView splash_image2 = (ImageView) findViewById(R.id.mediAware2);
Animation fade1 = AnimationUtils.loadAnimation(this, R.anim.fadein);
Animation fade2 = AnimationUtils.loadAnimation(this, R.anim.fadein2);
fade2.setAnimationListener(new AnimationListener() {
public void onAnimationEnd (Animation animation) {
Intent intent = new Intent(new Intent(MainActivity.this, MenuActivity.class));
startActivity(intent);
}
public void onAnimationStart(Animation animation){
}
public void onAnimationRepeat(Animation animation){
}
});
splash_image.startAnimation(fade1);
splash_image2.startAnimation(fade2);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
答案 0 :(得分:0)
我发现了我的问题。我错过了R.java文件。要添加文件,我只需在src中创建一个名为gen的文件夹然后清理项目,这就创建了R.java文件并删除了我的错误,感谢给出的帮助
