[英]android studio version 3.1.1
After updating my android studio to 3.1.1 I found the error in the picture. 将我的android studio更新到3.1.1后,我在图片中发现错误。 Before I updated android studio everything was fine.
在我更新android studio之前,一切都很好。
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class SetTimeActivity extends AppCompatActivity {
private int TIME_IN_MINUTES ;
private EditText et ;
private Button mButtonStartPause;
private Button mButtonReset;
private CountDownTimer mCountDownTimer;
private boolean mTimerRunning;
private long mTimeLeftInMillis;
private long mEndTime;
DevicePolicyManager devicePolicyManager;
ComponentName componentName;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_set_time);
et = (EditText) findViewById(R.id.setTimerMenu_et);
mButtonStartPause = (Button) findViewById(R.id.set_btn);
devicePolicyManager = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE);
componentName = new ComponentName(SetTimeActivity.this, Controller.class);
Try the following and check if it works : 请尝试以下操作,并检查其是否有效:
File -> Invalidate Caches and Restart
文件->使缓存无效并重新启动
Open up your command line and perform a manual gradle build : 打开命令行并执行手动Gradle构建:
./gradlew clean assemble ./gradlew清洁组装
Make sure you have the following in your build.gradle : 确保您的build.gradle中包含以下内容:
compile "com.android.support:appcompat-v7:{latest}"
Thank you for your answer but I got it Now, So they add dependencies to the gradle and we have to replace "compile" with "implementation", something like this , you can find everything you need in this URL : 谢谢您的回答,但我明白了,所以他们将依赖项添加到了gradle中,我们必须将“ compile”替换为“ implementation”,诸如此类,您可以在此URL中找到所需的一切:
