Question

我创建了一个自定义列表视图。在其布局中创建了一个编辑文本。但我无法编辑此编辑文本。

list.setAdapter(new yourAdapter(NewActivity.this, new String[] { "test1",
            "test2","test3" }));

我的yourAdapter类是

class yourAdapter extends BaseAdapter {

Context context;
String[] data;
private static LayoutInflater inflater = null;

public yourAdapter(Context context, String[] data) {
    // TODO Auto-generated constructor stub
    this.context = context;
    this.data = data;
    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return data.length;
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return data[position];
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}



@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    View vi = convertView;
    if (vi == null)
        for(int i =0; i<=getCount();i++){
            if(data[position].equals("grouped")){
                vi = inflater.inflate(R.layout.multipleselect, null);
            }
            else if(data[position].equals("kuchbhi"))
                vi = inflater.inflate(R.layout.yes_or_no, null);
            else {
                vi = inflater.inflate(R.layout.write_answer, null);
                //edit_text
                EditText edit_text = (EditText) vi.findViewById(R.id.edit_text);
            }


        }

   /* TextView text = (TextView) vi.findViewById(R.id.text);
    text.setText(data[position]);*/
    return vi;
}

}

我无法在edit_text中进行编辑。当我点击编辑文本键盘打开但没有显示内部编辑文本。

Marshmallow手动询问权限。毫无疑问，您必须已在清单文件中添加了位置权限，但现在您还需要添加一些代码以手动询问权限。您可以使用此库 https://github.com/Karumi/Dexter

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        if (checkPermission()) {
                            //do your work
                        } else {
                            requestPermission();
                        }
                    }
           }


            protected boolean checkPermission() {
                int result = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION);
                if (result == PackageManager.PERMISSION_GRANTED) {
                    return true;
                } else {
                    return false;
                }
            }

            protected void requestPermission() {

                if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.ACCESS_FINE_LOCATION)) {
                    Toast.makeText(this, "Write External Storage permission allows us to do store images. Please allow this permission in App Settings.", Toast.LENGTH_LONG).show();
                } else {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        requestPermissions(new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 100);
                    }
                }
            }

        @Override
        public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
            switch (requestCode) {
                case 100:
                    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                        //do your work
                    } else {
                        Log.e("value", "Permission Denied, You cannot use local drive .");
                    }
                    break;
            }
        }
