我正在尝试在LinearLayout中获取视图以填充宽度.我尝试使用LayoutParams设置它,但它给了我一个错误:

我的代码:

EditText et = new EditText(v.getContext());
                    et.setHint("asset ");
                    et.setTextSize(12);
                    et.setLayoutParams(new LayoutParams(
                            LayoutParams.WRAP_CONTENT,
                            LayoutParams.WRAP_CONTENT, 0.25f));
                    et.setPadding(0, 15, 0, 10);

错误 :

EditText et = new EditText(v.getContext());
                    et.setHint("asset ");
                    et.setTextSize(12);
                    et.setLayoutParams(new LayoutParams(
                            LayoutParams.WRAP_CONTENT,
                            LayoutParams.WRAP_CONTENT, 0.25f));
                    et.setPadding(0, 15, 0, 10);

我需要创建一个包含一些视图的linearLayout,当单击一个按钮时,thsi按钮被另一个活动中的动作触发,所以我使用了performClick,但它似乎不起作用; 这是我的代码:

Button click = new Button(rootView.getContext());
            SharedPreferences participant;
            Editor editor;

            SharedPreferences visible;
            Editor vis;
            participant = rootView.getContext().getSharedPreferences("participant", rootView.getContext().MODE_PRIVATE);
            visible = rootView.getContext().getSharedPreferences("visible", rootView.getContext().MODE_PRIVATE);

            editor = participant.edit();
            final String name= participant.getString("key", "toto");
            final String view = participant.getString("view","non");
            if(view.equalsIgnoreCase("yes")) click.performClick();

            click.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(final View v) {


                    // Creating a new LinearLayout
                    final LinearLayout ln = new LinearLayout(v.getContext());

                    // Setting the orientation to horizontal
                    ln.setOrientation(LinearLayout.HORIZONTAL);


                    formbis.addView(ln);

                    TextView tv1 = new TextView(v.getContext());
                    tv1.setText(name);
                    tv1.setTextSize(14);
                    tv1.setTypeface(null, Typeface.BOLD);
                    tv1.setPadding(0, 15, 0, 10); …

我正在使用一个方法:button_click(视图视图)在editText上设置文本,我有很多按钮,每个按钮都应该在特定的editText上设置文本.

有没有办法知道哪个按钮称为方法,以便我可以设置正确的editText文本？

这是方法的代码:

public void button_click(View view) {

            // Create the dialog
            final Dialog mDateTimeDialog = new Dialog(view.getContext());
            // Inflate the root layout
            LayoutInflater inflater = (LayoutInflater) view.getContext().getSystemService( Context.LAYOUT_INFLATER_SERVICE );
            final RelativeLayout mDateTimeDialogView = (RelativeLayout) inflater.inflate(R.layout.datepick, null);
            // Grab widget instance
            final DateTimePicker mDateTimePicker = (DateTimePicker) mDateTimeDialogView
                    .findViewById(R.id.DateTimePicker);
            mDateTimePicker.setDateChangedListener(this);

            // Update demo edittext when the "OK" button is clicked
            ((Button) mDateTimeDialogView.findViewById(R.id.SetDateTime))
                    .setOnClickListener(new OnClickListener() {
                        public void onClick(View v) {
                            mDateTimePicker.clearFocus();
                            // TODO Auto-generated method stub
                            String result_string = mDateTimePicker.getMonth()
                                    + …
