Question

喜我正在尝试动态创建多行文字。

RelativeLayout rel = (RelativeLayout) findViewById(R.id.layout_info);  
EditText tt = new EditText(getContext());  
tt.setId(100);  
RelativeLayout.LayoutParams rp = new RelativeLayout.LayoutParams(  
RelativeLayout.LayoutParams.WRAP_CONTENT,  
RelativeLayout.LayoutParams.FILL_PARENT);  
rp.addRule(RelativeLayout.BELOW, R.id.lbl_infotitle);  
rp.width = 0;  
tt.setTextColor(Color.BLACK);  
tt.setBackgroundColor(android.R.color.transparent);  
tt.setMaxLines(5);  
tt.setSingleLine(false);
tt.setGravity(Gravity.LEFT);  
tt.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE);  
tt.setText("This section helps to maintain the"  
                    + "Personal Profile of subscriber."  
                    + "Screen contains the link" + " to sub sections such as,");  
tt.setLayoutParams(rp);  
rel.addView(tt, new RelativeLayout.LayoutParams(
                LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));

但我的edittext始终只是单行。（不能获得包装效果）
如果有人提供解决方案，那就太棒了。它可能是多余的，但我提到了所有解决方案，没有任何动态。请帮助我实现这一目标。

添加到yout编辑文本textChangeListener并在重写方法中执行所需的操作。

例如

        edit.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {

        }



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

        }
    });
