您好我正在開發一個Android應用程序,沒有什麼花哨只是一些小的大學。當我使用R I最終位收到一個錯誤。例如R.id. mediAware 任何幫助將不勝感激。誤差android.R
這裏是我的代碼是否有幫助:
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);
}
}
嘗試做一個「乾淨的構建」,然後幫助重建。引用R文件時出錯 – moffeltje 2014-12-07 20:23:44
我做了一個清理和重建,現在所有活動都包含R的錯誤 – 2014-12-07 20:56:34
大多數情況下,當您遇到這種錯誤時,是因爲在您的XML佈局的其他地方出現錯誤,檢查你的佈局和清單的任何編碼錯誤。 – 2014-12-07 23:20:10
