Question

我正在构建一个应用程序，用于查看列表中的通话记录并在按列表中的项目时拨打电话。最佳选择是什么？我想尝试制作一个自定义适配器，但是我不确定这是正确的方法还是更简单的方法？

感谢您的帮助！

目前，我正在使用文本视图和字符串缓冲区来用我的通话记录填充列表。

public class LastCallActivity extends Activity {

    private List<LastCallModel> wlistCalls;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_last_call);

        if (ContextCompat.checkSelfPermission(LastCallActivity.this, Manifest.permission.READ_CALL_LOG) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(LastCallActivity.this, Manifest.permission.READ_CALL_LOG)) {
                ActivityCompat.requestPermissions(LastCallActivity.this, new String[]{Manifest.permission.READ_CALL_LOG}, 1);
            } else {
                ActivityCompat.requestPermissions(LastCallActivity.this, new String[]{Manifest.permission.READ_CALL_LOG}, 1);
            }
        } else {
            // do stuff
            TextView textView = (TextView) findViewById(R.id.textViewen);
            textView.setText(getCallDetails());
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case 1: {
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    if (ContextCompat.checkSelfPermission(LastCallActivity.this, Manifest.permission.READ_CALL_LOG) == PackageManager.PERMISSION_GRANTED) {
                        Toast.makeText(this, "Permission granted!", Toast.LENGTH_SHORT).show();
                        TextView textView = (TextView) findViewById(R.id.textViewen);
                        textView.setText(getCallDetails());

                    }
                } else {
                    Toast.makeText(this, "No permission GRANTED!", Toast.LENGTH_SHORT).show();
                }
                return;
            }
        }
    }

    private String getCallDetails() {
        StringBuffer sb = new StringBuffer();
        Cursor managedCursor = getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, null);
        int name = managedCursor.getColumnIndex(CallLog.Calls.CACHED_NAME);
        int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
        int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
        int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);
        int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);

        sb.append("Call Details:\n\n");

        while (managedCursor.moveToNext()) {
            String phName = managedCursor.getString(name);
            String phNumber = managedCursor.getString(number);
            String callType = managedCursor.getString(type);
            String callDate = managedCursor.getString(date);

            if (phName != null && phNumber != null) {
                wlistCalls.add(new LastCallModel(phName, phNumber));
            }

            Date callDayTime = new Date(Long.valueOf(callDate));
            SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yy HH:mm");
            String dateString = formatter.format(callDayTime);
            String callDuration = managedCursor.getString(duration);
            String dir = null;
            int dircode = Integer.parseInt(callType);

            switch (dircode) {
                case CallLog.Calls.OUTGOING_TYPE:
                    dir = "OUTGOING";
                    break;
                case CallLog.Calls.INCOMING_TYPE:
                    dir = "INCOMING";
                    break;
                case CallLog.Calls.MISSED_TYPE:
                    dir = "MISSED";
                    break;
            }

            sb.append("\nName: " + phName + "\nPhone Number: " + phNumber + " \nCallType: " + dir + "\nCall Date: " + dateString + "\nCall Duration: " + callDuration);

            sb.append("\n-------------");
            sb.append("\n*************");

            sb.append("\n*************");
        }

        managedCursor.close();
        return sb.toString();
    }
}

我通过使用带有自定义适配器的RecyclerView解决了该问题！

这是我的自定义适配器。

public class LastCallAdapter extends RecyclerView.Adapter<LastCallAdapter.ViewHolder> {

private LayoutInflater layoutInflater;
private Context mContext;
private ArrayList<String> phoneNumber;

public LastCallAdapter(Context mContext, ArrayList<String> phoneNumber) {
    this.mContext = mContext;
    this.phoneNumber = phoneNumber;
}


@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    View view = layoutInflater.from(parent.getContext()).inflate(R.layout.items_contacts, parent, false);
    ViewHolder holder = new ViewHolder(view);
    return holder;
}

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

    holder.number.setText(phoneNumber.get(position));

    holder.parentLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent callDial = new Intent(Intent.ACTION_DIAL);
            callDial = callDial.setData(Uri.parse("tel:"+phoneNumber.get(position)));
            if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                mContext.startActivity(callDial);
                return;
            }
            Toast.makeText(mContext, phoneNumber.get(position), Toast.LENGTH_SHORT).show();
        }
    });

}

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

public class ViewHolder extends RecyclerView.ViewHolder{

    TextView number;
    LinearLayout parentLayout;

    public ViewHolder(View itemView) {
        super(itemView);

        number = itemView.findViewById(R.id.contact_number);
        parentLayout = itemView.findViewById(R.id.parent_layout);

    }
}



}

主要活动中用于启动适配器的方法

 private void startAdapter(){
    RecyclerView recyclerView = findViewById(R.id.recyclerViewen);
    LastCallAdapter lastCallAdapter = new LastCallAdapter(this, phoneNumbers);
    recyclerView.setAdapter(lastCallAdapter);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));

}

如何将通话记录中的号码填充到onClick列表中？
