我們如何在android中以編程方式划分兩個相等寬度的屏幕

Question

我正在開發Android應用程序，但基於屏幕尺寸元素大小變化。有任何解決方案，以平均划分屏幕尺寸。我在不同的屏幕，如5英寸和3.7英寸獲得不同的大小

我的代碼是......

lView.setBackgroundColor(Color.parseColor("#FFFFFF"));
 lView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
 LinearLayout.LayoutParams layoutParams2 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, 220);
 GradientDrawable gdtitle = new GradientDrawable();

 gdtitle.setCornerRadius(5);
 ImageView title = new ImageView(Main2Activity.this);
 title.setImageResource(R.drawable.logo);
 title.setLayoutParams(layoutParams2);
 title.setBackgroundDrawable(gdtitle);
 lView.setOrientation(LinearLayout.VERTICAL);
 lView.addView(title);


 GradientDrawable gd = new GradientDrawable();
 gd.setColor(Color.parseColor("#FFFFFF")); // Changes this drawbale to use a single color instead of a gradient
 gd.setCornerRadius(5);
 gd.setStroke(1, 0xFF000000);

  int width = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 200, getResources().getDisplayMetrics());
  int Height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 50, getResources().getDisplayMetrics());
  TextView uname1 = new TextView(Main2Activity.this);
  uname1.setText("Hello , " + Sessionname);
  uname1.setGravity(Gravity.CENTER);
  uname1.setTextColor(Color.parseColor("#003366"));
  uname1.setTextSize(20);
  uname1.setWidth(width);
  uname1.setLayoutParams(l2);

  et1 = new TextView(Main2Activity.this);
  et1.setHeight(Height);
  et1.setWidth(width);
  et1.setTextColor(Color.WHITE);
  et1.setHintTextColor(Color.WHITE);
  et1.setGravity(Gravity.CENTER);
  et1.setHint("Select Date");
  et1.setBackgroundDrawable(gd3);
  et1.setTextSize(15);
  et1.setLayoutParams(l2);

  LinearLayout.LayoutParams l4 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  l4.gravity = Gravity.CENTER;
  lHorizontalView1.setOrientation(LinearLayout.HORIZONTAL);
  lHorizontalView1.setLayoutParams(l4);
  lHorizontalView1.addView(uname1);
  lHorizontalView1.addView(et1);
  lView.addView(lHorizontalView1);



  GradientDrawable gd4 = new GradientDrawable();
  gd4.setCornerRadius(30);
  gd4.setColor(Color.parseColor("#5CB85C"));
  gd4.setStroke(3, 0xFFFFFFFF);

  Intime = new TextView(Main2Activity.this);
  Intime.setHint("In Time");
  Intime.setTextColor(Color.WHITE);
  Intime.setHintTextColor(Color.WHITE);
  Intime.setTextSize(15);
  Intime.setHeight(Height);
  Intime.setWidth(width);
  Intime.setGravity(Gravity.CENTER);
  Intime.setLayoutParams(l2);
  Intime.setBackgroundDrawable(gd4);
  lView.setOrientation(LinearLayout.HORIZONTAL);

   Outtime = new TextView(Main2Activity.this);
   Outtime.setHint("Out Time");
   Outtime.setTextSize(15);
   Outtime.setHeight(Height);
   Outtime.setWidth(width);
   Outtime.setGravity(Gravity.CENTER);
   Outtime.setTextColor(Color.WHITE);
   Outtime.setHintTextColor(Color.WHITE);
   Outtime.setLayoutParams(l2);
   Outtime.setBackgroundDrawable(gd4);
   lView.setOrientation(LinearLayout.HORIZONTAL);

   LinearLayout lHorizontalView = new LinearLayout(Main2Activity.this);
   LinearLayout.LayoutParams l3 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
   l3.gravity = Gravity.CENTER;


   lHorizontalView.setOrientation(LinearLayout.HORIZONTAL);
   lHorizontalView.setLayoutParams(l3);
   lHorizontalView.addView(Intime);
   lHorizontalView.addView(Outtime);
   lView.addView(lHorizontalView);

Answer 1

您應該使用DisplayMetrics

 DisplayMetrics metrics = getResources().getDisplayMetrics();

    int DeviceTotalWidth = metrics.widthPixels;
    int DeviceTotalHeight = metrics.heightPixels;

例

 RelativeLayout rl_firstObj=(RelativeLayout)findViewById(R.id.rl_first);
 rl_firstObj.getLayoutParams().width=DeviceTotalWidth*50/100;

 RelativeLayout rl_secondObj=(RelativeLayout)findViewById(R.id.rl_second);
 rl_secondObj.getLayoutParams().width=DeviceTotalWidth*50/100;

Answer 2

對於按鈕父視圖，使用linearlayout和set

param.weight = 1

對於每個按鈕。

Answer 3

使用LinearLayouts並為其中的視圖指定權重將使用相同的比例將視圖分開，無論屏幕大小如何。 在這里，我已經為兩個視圖分配了權重1，因此它們將在我的旁邊顯示在屏幕上。

<LinearLayout
    android:id="@+id/linearLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="2">

    <Button
        android:id="@+id/button1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Button1"
        android:textSize="16sp" />

    <Button
        android:id="@+id/button2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Button2"
        android:textSize="16sp" />
</LinearLayout>

Answer 4

 LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, 1);

        textView1.setLayoutParams(layoutParams);

        LinearLayout.LayoutParams layoutParams1 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT, 1);

        textView2.setLayoutParams(layoutParams1);

我采用線性布局，參數權重為1，並將其划分為兩個視圖。在這里我使用了文本視圖你可以在你的代碼中查看任何視圖。如果遇到任何問題請告訴我
