Alignment of dynamic views

问题

I want the alignment of the editext and the imageviewin the same horizontal line but I am getting the imageview below the edittext.

main fragment code

 final LinearLayout lnrView = (LinearLayout) 
 child.findViewById(R.id.lnrView);
                Button btnad = (Button) child.findViewById(R.id.btnad);
                btnad.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        lnrView.addView(newedittext());
                        lnrView.addView(newImageview(getActivity()));
                    }
                });

neweditext method

  private View newedittext() {
    final ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    final EditText editText = new EditText(getActivity());
    int id = 0;
    editText.setId(id);
    editText.setTextSize(14);
    editText.setTextColor(Color.rgb(0, 0, 0));
    editText.setMaxEms(2);
    editText.setInputType(InputType.TYPE_CLASS_TEXT);
    return editText;
}

newImageview method

 public ImageView newImageview(Context context) {
    final ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    final ImageView imgView = new ImageView(context);
    int id = 0;
    imgView.setId(id);
    imgView.setImageDrawable(context.getResources().getDrawable(R.drawable.ic_close_red));
    return imgView;
}

main fragment xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

回答1:

You need add first a Horizontal Linearlayout in Your lnrView than add EditText and Imageview

Try this

 button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            LinearLayout layout = new LinearLayout(MainActivity.this);
            layout.setOrientation(LinearLayout.HORIZONTAL);
            LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
                    LinearLayout.LayoutParams.WRAP_CONTENT);

            layout.setLayoutParams(lp);
            layout.addView(newedittext());
            layout.addView(newImageview(MainActivity.this));

            lnrView.addView(layout);
        }
    });

回答2:

Or simpler use

ListView

with

ArrayAdapter

where you define you own layout (EditText and button)

There is better way to manage add and remove lines.

Also you have all EditTexts in one array and you can do your logic simpler.
