Следующий способ, который я использовал для открытия файла в блокноте, который я сохранил в своей исходной папке.Экран становится пустым, а приложение закрывает себя
Когда я открываю этот метод, открывается новый пустой экран (полностью черный), и сила приложения закрывается.
public class Fest1 extends AppCompatActivity {
TextView text;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fest1);
text=(TextView)findViewById(R.id.textV);
text.setText(readTxt());
}
private String readTxt(){
InputStream inputStream=getResources().openRawResource(R.raw.text);
ByteArrayOutputStream byteArrayOutputStream=new ByteArrayOutputStream();
int i;
try{
i=inputStream.read();
while (i!=1)
{
byteArrayOutputStream.write(i);
i = inputStream.read();
}
inputStream.close();
}catch (IOException e)
{
e.printStackTrace();
}
return byteArrayOutputStream.toString();
}
}
