从视图中获取编辑文本值(get edit text value from view)

我想从动态创建bean的每个视图中获取editext值和位图图像。我没有得到如何使用它。我试图从视图vx获取详细信息。但它没有发生。这是我的代码。

请帮忙...

public class MainActivity extends Activity {

EditText textIn;
Button buttonAdd;
LinearLayout container;
View addView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final ArrayList<String> value=new ArrayList<String>();
    textIn = (EditText)findViewById(R.id.textin);
    buttonAdd = (Button)findViewById(R.id.add);
   Button button = (Button)findViewById(R.id.all);
    container = (LinearLayout)findViewById(R.id.container);
    button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {

            for (int i = 0, c = container.getChildCount(); i < c; i++) {

                View vx = container.getChildAt(i);

            }
        }
    });

    buttonAdd.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View arg0) {
            LayoutInflater layoutInflater = 
                    (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            addView = layoutInflater.inflate(R.layout.row, null);
            EditText textOut = (EditText)addView.findViewById(R.id.textout);
            textOut.setText(textIn.getText().toString());
            textOut.addTextChangedListener(new TextWatcher() {
                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {

                    // TODO Auto-generated method stub

                }

                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                    // TODO Auto-generated method stub
                }

                @Override
                public void afterTextChanged(Editable s) {



                }
            });
            final ImageView buttonimg = (ImageView)addView.findViewById(R.id.remove);
            buttonimg.setOnClickListener(new OnClickListener(){

                @Override
                public void onClick(View v) {
                    //((LinearLayout)addView.getParent()).removeView(addView);
                    buttonimg.setImageResource(R.drawable.logo);
                }});

            container.addView(addView);
        }});


}

}


I want to get the editext value and bitmap image from the every view that has bean created dynamically.I am not getting how to use it.I have tried to get the details from view vx.But it's not happening.Here is my code.

Please help...

public class MainActivity extends Activity {

EditText textIn;
Button buttonAdd;
LinearLayout container;
View addView;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final ArrayList<String> value=new ArrayList<String>();
    textIn = (EditText)findViewById(R.id.textin);
    buttonAdd = (Button)findViewById(R.id.add);
   Button button = (Button)findViewById(R.id.all);
    container = (LinearLayout)findViewById(R.id.container);
    button.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {

            for (int i = 0, c = container.getChildCount(); i < c; i++) {

                View vx = container.getChildAt(i);

            }
        }
    });

    buttonAdd.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View arg0) {

                    (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            addView = layoutInflater.inflate(R.layout.row, null);
            EditText textOut = (EditText)addView.findViewById(R.id.textout);
            textOut.setText(textIn.getText().toString());
            textOut.addTextChangedListener(new TextWatcher() {
                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {

                    // TODO Auto-generated method stub

                }

                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                    // TODO Auto-generated method stub
                }

                @Override

            });
            final ImageView buttonimg = (ImageView)addView.findViewById(R.id.remove);
            buttonimg.setOnClickListener(new OnClickListener(){

                @Override
                public void onClick(View v) {
                    //((LinearLayout)addView.getParent()).removeView(addView);
                    buttonimg.setImageResource(R.drawable.logo);

最满意答案

用于检索文本:

((EditText)vx.findViewById(R.id.textout)).getText()

For retrieving the text:
