我有问题。我创建了一个新活动,我试图将其链接起来
我之前的那个。我创建了一个意图,该应用程序没有给出
我的错误,但在电话上我收到了这条消息:Waiting for Debugger: force close
我必须关闭它。
有任何建议吗?
在意图中我也尝试了这个:Intent intent = new Intent(StartScreen.this, MainActivity.class);
然后,我有这个错误:
no suitable constructor found for Intent(<anonymous OnClickListener>,Class<MainActivity>) constructor Intent.Intent(String,Uri) is not applicable (argument mismatch; <anonymous OnClickListener> cannot be converted to String) constructor Intent.Intent(Context,Class<?>) is not applicable (argument mismatch; <anonymous OnClickListener> cannot be converted to Context)
这是代码:
public class StartScreen extends AppCompatActivity {
public static final String TAG = "StartScreen";
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.start);
Log.d(TAG, "onClick: Starting.");
Button startBtn = (Button) findViewById(R.id.startBtn);
startBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "onClick: clicked startBtn.");
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
}
});
}
}
