我在我的应用程序中使用 v7-appcompat 作为库，我使用 IntelliJ-IDEA 并在项目目录中导入了 appcompat 库。自从我收到自动完成建议并且项目没有显示错误以来，该库已被集成，我正在使用主题“Theme.AppCompat.Light.DarkActionBar”，该主题也工作正常，当我在当实现“ActionBarActivity”的 Activity 被触发时，模拟器崩溃，实现“Activity”的其余 Activity 在实现的 AppCompat 主题下运行良好。
此 Activity 运行良好:
import android.app.Activity;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.ShareActionProvider;
public class home extends Activity{
private ShareActionProvider mShareActionProvider;
Button btnPoetry;
Button btnProse;
Button btnBiography;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
btnPoetry = (Button) findViewById(R.id.btnPoetry);
btnPoetry.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(home.this, poetry.class);
startActivity(i);
}
});
btnProse = (Button) findViewById(R.id.btnProse);
btnProse.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(home.this, prose.class);
startActivity(i);
}
});
btnBiography = (Button) findViewById(R.id.btnBiography);
btnBiography.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(home.this, biography.class);
startActivity(i);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.main_menu, menu);
MenuItem item = menu.findItem(R.id.menu_item_share);
mShareActionProvider = (ShareActionProvider) item.getActionProvider();
mShareActionProvider.setShareIntent(getDefaultIntent());
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.settings:
break;
case R.id.legend:
break;
case R.id.aboutUs:
break;
}
return super.onOptionsItemSelected(item);
}
private Intent getDefaultIntent(){
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
intent.putExtra(Intent.EXTRA_TEXT, "Extra Text");
return intent;
}
}
此类 Activity 会崩溃:

最佳答案
确保执行以下操作 ( from Support Library Setup ):
Right-click the library project folder and select Build Path > Configure Build Path.
In the Order and Export tab, check the .jar files you just added to the build path, so they are available to projects that depend on this library project. For example, the appcompat project requires you to export both the android-support-v4.jar and android-support-v7-appcompat.jar files.
Uncheck Android Dependencies.
