私のレイアウトでは、追加ボタンをクリックして2つの編集テキストを追加し、その追加(機能)し、削除ボタンをクリックすると動的編集テキストも削除されます.私の質問は、動的に2つ追加すると仮定して、そこから文字列値を取得する方法です.不要な場合は削除します。ここに私のコードがあります..

public class PartDetails extends AppCompatActivity {

    // Parent view for all rows and the add button.
    private LinearLayout mContainerView;
    // The "Add new" imageButton
    private ImageButton mAddImageButton;
    Button submit_part_details;
    private View mExclusiveEmptyView;
    EditText prequired,pnumber;

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

        mContainerView = (LinearLayout) findViewById(R.id.parentView);
        submit_part_details = (Button) findViewById(R.id.submit_part_details);
        mAddImageButton = (ImageButton) findViewById(R.id.add_et_parts);
        prequired= (EditText) findViewById(R.id.et_Prequired);
        pnumber= (EditText) findViewById(R.id.et_Pnumber);
        mAddImageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                inflateEditRow();
            }
        });
        submit_part_details.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String parts=prequired.getText().toString();
                String pnum =pnumber.getText().toString();
            }
        });
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);

        // TODO: Handle screen rotation:
        // encapsulate information in a parcelable object, and save it
        // into the state bundle.

    }
    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        // TODO: Handle screen rotation:
        // restore the saved items and inflate each one with inflateEditRow;

    }

    // Helper for inflating a row
    private void inflateEditRow() {

        LayoutInflater layoutInflater =
                (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        final View addView = layoutInflater.inflate(R.layout.row_add_parts, null);
        final EditText parts_required = (EditText) addView
                .findViewById(R.id.et_parts);
        final EditText parts_number = (EditText) addView
                .findViewById(R.id.et_Pnumber);
        final ImageButton deleteButton = (ImageButton) addView
                .findViewById(R.id.delete_et_parts);
        deleteButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                ((LinearLayout) addView.getParent()).removeView(addView);
            }
        });

        mContainerView.addView(addView);
    }
}

        @Override

            ((LinearLayout) addView.getParent()).removeView(addView);
        }
    });

    mContainerView.addView(addView);
}

When you delete the inflated row remove the element from collection too 

Loop through your Collection and get the text from dynamic EditText
for(int i=0;i<edtParts_required.size();i++){
   String enterdText=edtParts_required.get(i).getText().toString();
}
