无法从项目单击启动片段

Question

我在按下某个项目时尝试启动片段，但应用程序崩溃了。

这是我的代码：

活动java：

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.RelativeLayout;
import android.widget.FrameLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;


public class AccountActivity extends AppCompatActivity {

    private String carrierName;


    private RelativeLayout lcb;
    private RelativeLayout layoutBalanceLoad;
    private RelativeLayout layoutCreditShare;
    private RelativeLayout layoutCreditBarrow;
    private FrameLayout dashboardProgressBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_account);


        lcb = (RelativeLayout) findViewById(R.id.layout_balance_check);
        layoutBalanceLoad = (RelativeLayout) findViewById(R.id.layout_balance_load);
        layoutCreditShare = (RelativeLayout) findViewById(R.id.layout_credit_share);
        layoutCreditBarrow = (RelativeLayout) findViewById(R.id.layout_credit_barrow);
        dashboardProgressBar = (FrameLayout) findViewById(R.id.dashboard_progress_bar);


    }

    public void checkBalance(View view) {

            Fragment fragment = new CheckBalance();
            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
            transaction.replace(R.id.fragment_container, fragment).commitAllowingStateLoss();


    }
}

究竟是什么错误？

java.lang.IllegalArgumentException: Expected receiver of type com.esqmo.apps.mosungiplus.AccountActivity, but got android.view.ContextThemeWrapper at java.lang.reflect.Method.invoke(Native Method) at android.view.View$DeclaredOnClickListener.onClick(View.java:4735) 

Answer 1

这一次尝试将onClicklistener设置为RelativeLayout in onCreate：

首先，从xml代码中删除 android:onClick="checkBalance"。然后按以下步骤操作：

lcb.setOnClickListener(new View.OnClickListener(){          
            @Override
            public void onClick(View view) {
                 Fragment fragment = new CheckBalance();
                 FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
                 transaction.replace(R.id.fragment_container, fragment).commitAllowingStateLoss();
            }                
        });

要按后退按钮上的片段，首先全局声明FragmentManager：

 FragmentManager fm;

接下来，在您的代码下方替换：

 Fragment fragment = new CheckBalance();
 FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
 transaction.replace(R.id.fragment_container, fragment).commitAllowingStateLoss();

有了这个：

 Fragment fragment = new CheckBalance();
 fm = getSupportFragmentManager();
 FragmentTransaction ft = fm.beginTransaction();
 ft.addToBackStack("Your Fragment Tag");
 ft.add(R.id.fragment_container, fragment);
 ft.commit();

最后，覆盖您的onBackPressed()活动：

 @Override
 public void onBackPressed() {
     if (fm.getBackStackEntryCount() > 0)
        fm.popBackStackImmediate();
     else super.onBackPressed();
 }
