Question

private void textview(String question) {
    TextView clientAddress = new TextView(this);
    clientName.setGravity(1);
    clientAddress.setTypeface(Typeface.defaultFromStyle(1));
    clientAddress.setText(question);
    clientAddress.setLayoutParams(lparams);
    linearLayout.addView(clientAddress);
    clientAddress.setTextSize(20);
    clientAddress.setTextColor(getResources().getColor(R.color.white));
    clientAddress.setPadding(7, 10, 0, 10);
}

我正在调用此函数来动态创建6个TextView。但我很困惑，如何从这些TextViews获取文本。谁能建议我解决方案？

Answer 1

您可以使用gettext（）方法从文本视图中获取文本。如果你想将获取的文本转换为字符串，那么你可以使用tostring（）。

String fetchedtext = clientAddress.getText().toString();

Answer 2

您必须为每个TextView创建一个不同的对象。使用这些对象后，您可以获得TextView的值。使用getText()的{{1}}属性。

您还可以创建TextView的数组。

Answer 3

做这样的事情

private void textview(int position, String question) {
        TextView clientAddress = new TextView(this);
        clientName.setGravity(1);
        clientAddress.setTypeface(Typeface.defaultFromStyle(1));
        clientAddress.setText(question);
        clientAddress.setTag(position);
        clientAddress.setLayoutParams(lparams);
        linearLayout.addView(clientAddress);
        clientAddress.setTextSize(20);
        clientAddress.setTextColor(getResources().getColor(R.color.white));
        clientAddress.setPadding(7, 10, 0, 10);
    }

  public String getTextFromTextView(int positionOfTextView , LinearLayout mLinearLayout){
    String result = "";
    for (int i = 0; i <((ViewGroup)mLinearLayout).getChildCount() ; i++) {
        if(((ViewGroup) mLinearLayout).getChildAt(i)!=null ){
            View mView =((ViewGroup) mLinearLayout).getChildAt(i);
            if(mView instanceof  TextView){
                TextView mTextView = (TextView)mView;
                if(mTextView!=null && mTextView.getTag()!=null && positionOfTextView==(int) mTextView.getTag() ){
                    result =mTextView.getText().toString();
                }
            }else {
                TextView mTextView =  (TextView) mView.findViewWithTag(positionOfTextView);
                if(mTextView!=null){
                    result =mTextView.getText().toString();
                }
            }
        }
    }
    return result;
}
