Question

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);
        }});


}

}

Answer 1

我发布了答案，因为我还没有得到关于如何获取imagebitmap的答案。这段代码正在运行

         ImageView v2=((ImageView) vx.findViewById(R.id.remove));
         Bitmap bm=((BitmapDrawable)v2.getDrawable()).getBitmap();

Answer 2

用于检索文本：

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

从视图中获取编辑文本值
