Question

在我的布局中，我添加了两个编辑文本，点击添加按钮并添加（工作），当我点击删除按钮时，它也删除动态编辑文本。我的问题是如何从中获取字符串值假设我动态添加两个视图，并在不需要时删除。这是我的代码..

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);
    }
}

Answer 1

你可以通过多种方式做到这一点。这里有两个：

制作一个ArrayList，每当你添加新的编辑文本时，也将它添加到这个数组中，当你删除时也将它从这里删除。当你想让他们的文字把它放在一个for循环中

更好的方式：你有一个线性布局。得到它的子计数并将其置于for循环中。像这样：

    for (int i=0;i<mContainerView.getChildCount();i++){
        View mView=mContainerView.getChildAt(i);
        EditText myEditText=(EditText) mView.findViewById(R.id.et_parts);
        String txt=myEditText.getText().toString();
        EditText myEditText2=(EditText) mView.findViewById(R.id.et_Pnumber);
        String txt2=myEditText2.getText().toString();
    }

Answer 2

  ArrayList<EditText> edtParts_required=new ArrayList<EditText>();
  ArrayList<EditText> edtParts_number=new ArrayList<EditText>();

// 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);

    //Add EditText object to Collection 
     edtParts_required.add(parts_required);
     edtParts_number.add(parts_required);

    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);
}

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();
}

如何从动态编辑文本中检索字符串值..？
