從recyclerview調用新的意圖Intent_ActionCall

-2

我有一個回收站視圖，並且想要調用一個用edittext holder.textPhone編寫的電話號碼。但是，當調用Intent.Action_Call時，應用程序會一直停止。我的代碼中有什麼錯誤？從recyclerview調用新的意圖Intent_ActionCall

這是我的userAdapter類，其中包含recyclerview。

package com.example.mher.citygo; 

import android.content.Context; 
import android.content.Intent; 
import android.content.pm.PackageManager; 
import android.support.v4.app.ActivityCompat; 
import android.support.v7.widget.RecyclerView; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.TextView; 

import java.util.List; 

public class UserAdapter extends 
RecyclerView.Adapter<UserAdapter.UserViewHolder> { 

private List<UserModel> list; 

public UserAdapter(List<UserModel> list) { 
    this.list = list; 
} 

@Override 
public UserViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    return new UserViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.view_item, parent, false)); 
} 

@Override 
public void onBindViewHolder(final UserViewHolder holder, int position) { 

    UserModel user = list.get(position); 
    holder.textFrom.setText(user.from); 
    holder.textTo.setText(user.to); 
    holder.textDate.setText(user.date); 
    holder.textPhone.setText(user.phone); 
    holder.textPhone.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Context context = v.getContext(); 
      Intent intent = new Intent(Intent.ACTION_CALL); 
      if (ActivityCompat.checkSelfPermission(context, android.Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) { 
       context.startActivity(intent); 
       return; 
      } 


     } 
    }); 


} 

@Override 
public int getItemCount() { 
    return list.size(); 
} 

class UserViewHolder extends RecyclerView.ViewHolder 
{ 
    TextView textFrom,textTo,textDate,textPhone; 

    public UserViewHolder(View itemView) { 
     super(itemView); 
     textFrom=(TextView) itemView.findViewById(R.id.text_from); 
     textTo=(TextView) itemView.findViewById(R.id.text_to); 
     textDate=(TextView) itemView.findViewById(R.id.text_date); 
     textPhone=(TextView) itemView.findViewById(R.id.phonenumber); 
    } 
} 
}

logcat的

PLZ後logcat的錯誤 –

沒有ü添加PHONE_CALL許可清單中？ –

是的權限被添加 –

你在錯誤的地方加入startActivity，添加它，如果條件變更後該行

holder.textPhone.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     Context context = v.getContext(); 
     Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "1324567890")); 
     if (ActivityCompat.checkSelfPermission(context, android.Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) { 
      Toast.makeText(this, "permission not granted", Toast.LENGTH_SHORT).show(); 
      ActivityCompat.requestPermissions(this, 
       new String[]{Manifest.permission.CALL_PHONE},143); 
     }else{ 
      context.startActivity(intent); 
      } 


    } 
});

調用startActivity()上v.getContext()似乎這裏導致錯誤。嘗試添加以下標誌您intent調用startActivity()前：

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

它沒有工作 –

@KarenMkhitaryan您發佈了不正確的日誌。應用程序崩潰時發佈錯誤日誌。 – Shaishav

發佈了正確的logcat抱歉 –

檢查了這一點

Intent callIntent = new Intent(Intent.ACTION_CALL); //use ACTION_CALL class 
callIntent.setData(Uri.parse("tel:" + user.phone)); //this is the phone number calling 
     //check permission 
     //If the device is running Android 6.0 (API level 23) and the app's targetSdkVersion is 23 or higher, 
     //the system asks the user to grant approval. 
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) { 
      //request permission from user if the app hasn't got the required permission 
      ActivityCompat.requestPermissions(this, 
        new String[]{Manifest.permission.CALL_PHONE}, //request specific permission from user 
        10); 
      return; 
}else {  //have got permission 
      try{ 
       startActivity(callIntent); //call activity and make phone call 
      } 
      catch (android.content.ActivityNotFoundException ex){ 
       Toast.makeText(getApplicationContext(),"yourActivity is not founded",Toast.LENGTH_SHORT).show(); 
      } 
}
