从LinearLayout中设置两个按钮编程之间的保证金 [英] Set a Margin between two buttons programmatically from a linearlayout

问题描述

如何设置的20dp按钮Regler公司和decommender编程之间的余量。

这是我的工作方式

 的LinearLayout lytmain =新的LinearLayout（Mcontex）;
            lytmain.setOrientation（LinearLayout.VERTICAL）;
            的LinearLayout lytdate =新的LinearLayout（Mcontex）;
            的LinearLayout lytbutton =新的LinearLayout（Mcontex）;
            lytbutton.setBackgroundResource（R.color.black）;



            lytbutton.setBackgroundResource（R.color.black）;
            lytdate.setBackgroundResource（R.color.black）;
            lytmain.setBackgroundResource（R.color.black）;
            按钮btnset =新按钮（Mcontex）;
            按钮btncancel =新按钮（Mcontex）;


            btncancel.setShadowLayer（2，1，1，R.color.black）;
            btnset.setShadowLayer（2，1，1，R.color.black）;
            btnset.setBackgroundResource（R.drawable.black_button）;
            btncancel.setBackgroundResource（R.drawable.black_button）;

            btnset.setTextColor（Mcontex.getResources（）的getColor（R.color.white））;
            btncancel.setTextColor（Mcontex.getResources（）的getColor（R.color.white））;
            btncancel.setTextSize（15）;
            btnset.setTextSize（15）;
            btnset.setText（Regler公司）;
            btncancel.setText（Décommander）;

            btnset.setGravity（Gravity.CENTER）;
            btncancel.setGravity（Gravity.CENTER）;

            最后WheelView月=新WheelView（Mcontex）;
            最后WheelView年=新WheelView（Mcontex）;
            最后WheelView天=新WheelView（Mcontex）;

            lytdate.addView（天，新的LayoutParams（
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，1.2F））;
            lytdate.addView（月，新的LayoutParams（
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，0.8f））;

            lytdate.addView（一年，新的LayoutParams（
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，1F））;
            requestWindowFeature（Window.FEATURE_NO_TITLE）;



            lytbutton.addView（btnset，新的LayoutParams（
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，1.5F））;

            lytbutton.addView（btncancel，新的LayoutParams（
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT，1.5F））;


            lytbutton.setPadding（5,5，5,5）;
            lytmain.addView（lytdate）;
            lytmain.addView（lytbutton）;

            的setContentView（lytmain）;

            getWindow（）。setLayout的（LayoutParams.FILL_PARENT，
                    LayoutParams.WRAP_CONTENT）;
 

解决方案

使用LinearLayout.LayoutParams

<一个href="http://developer.android.com/reference/android/widget/LinearLayout.LayoutParams.html">http://developer.android.com/reference/android/widget/LinearLayout.LayoutParams.html

您可以setMargins到的LayoutParams，然后setLayoutParams你的看法。

  LinearLayout.LayoutParams PARAMS =新LinearLayout.LayoutParams（
                LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT）;
params.setMargins（0,2，0,0）;
button.setLayoutParams（PARAMS）;
 

How can i set a margin of 20dp between the button "regler" and "decommender" programmatically.

Here is my workings

 LinearLayout lytmain = new LinearLayout(Mcontex);
            lytmain.setOrientation(LinearLayout.VERTICAL);
            LinearLayout lytdate = new LinearLayout(Mcontex);
            LinearLayout lytbutton = new LinearLayout(Mcontex);
            lytbutton.setBackgroundResource(R.color.black);



            lytbutton.setBackgroundResource(R.color.black);
            lytdate.setBackgroundResource(R.color.black);
            lytmain.setBackgroundResource(R.color.black);
            Button btnset = new Button(Mcontex);
            Button btncancel = new Button(Mcontex);


            btncancel.setShadowLayer(2, 1, 1, R.color.black);
            btnset.setShadowLayer(2, 1, 1, R.color.black);
            btnset.setBackgroundResource(R.drawable.black_button);
            btncancel.setBackgroundResource(R.drawable.black_button);

            btnset.setTextColor(Mcontex.getResources().getColor(R.color.white));
            btncancel.setTextColor(Mcontex.getResources().getColor(R.color.white));
            btncancel.setTextSize(15);
            btnset.setTextSize(15);
            btnset.setText("Régler");
            btncancel.setText("Décommander");

            btnset.setGravity(Gravity.CENTER);
            btncancel.setGravity(Gravity.CENTER);

            final WheelView month = new WheelView(Mcontex);
            final WheelView year = new WheelView(Mcontex);
            final WheelView day = new WheelView(Mcontex);

            lytdate.addView(day, new LayoutParams(
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT, 1.2f));
            lytdate.addView(month, new LayoutParams(
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT, 0.8f));

            lytdate.addView(year, new LayoutParams(
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT, 1f));
            requestWindowFeature(Window.FEATURE_NO_TITLE);



            lytbutton.addView(btnset, new LayoutParams(
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT,1.5f));

            lytbutton.addView(btncancel, new LayoutParams(
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
                    android.view.ViewGroup.LayoutParams.WRAP_CONTENT, 1.5f));


            lytbutton.setPadding(5, 5, 5, 5);
            lytmain.addView(lytdate);
            lytmain.addView(lytbutton);

            setContentView(lytmain);

            getWindow().setLayout(LayoutParams.FILL_PARENT,
                    LayoutParams.WRAP_CONTENT);

解决方案

Use LinearLayout.LayoutParams

http://developer.android.com/reference/android/widget/LinearLayout.LayoutParams.html

You can setMargins to LayoutParams, then setLayoutParams to your view.

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params.setMargins(0, 2, 0, 0);
button.setLayoutParams(params);
