我有一款應用程序，可以縮放Android手機上多種屏幕尺寸的圖像。調整圖像大小以適應多種屏幕尺寸
佈局以編程方式創建（無xml），我只是在將圖片保存在我的照片編輯器中時定義圖片的大小，例如60x60。
它似乎儘可能在平板電腦上擴大規模，但可能會更大。 我嘗試將圖像大小更改爲100x100，這會使平板電腦屏幕更加平滑，但現在它不會在較小的設備上縮小該圖像......非常令人沮喪。
這裏是我的代碼：
Android Manifest: enabling resizable attribute and supported screens
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.anndconsulting.numbertouch"
android:versionCode="1"
android:versionName="1.0"
android:installLocation="auto"
android:resizeable="true"
>
<supports-screens
android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:anyDensity="true"
/>
Game.Java代碼：
//create a layout
ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setBackgroundResource(R.drawable.background);
ll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
//create another 5 linear layouts which will host 5 buttons horizontally
linearLayout1 = new LinearLayout(this);
linearLayout1.setOrientation(LinearLayout.HORIZONTAL);
linearLayout1.setGravity(Gravity.CENTER);
linearLayout2 = new LinearLayout(this);
linearLayout2.setOrientation(LinearLayout.HORIZONTAL);
linearLayout2.setGravity(Gravity.CENTER);
linearLayout3 = new LinearLayout(this);
linearLayout3.setOrientation(LinearLayout.HORIZONTAL);
linearLayout3.setGravity(Gravity.CENTER);
linearLayout4 = new LinearLayout(this);
linearLayout4.setOrientation(LinearLayout.HORIZONTAL);
linearLayout4.setGravity(Gravity.CENTER);
linearLayout5 = new LinearLayout(this);
linearLayout5.setOrientation(LinearLayout.HORIZONTAL);
linearLayout5.setGravity(Gravity.CENTER);
Then i create a 5x5 array of buttons (which I saved as 100x100) in the drawable folder
for (int i = 0; i < 25; i++) {
buttonsa.add(createButton(i));
}
Collections.shuffle(buttonsa);
//add first 5 buttons to first layout
for (int i=0;i<5;i++) {
linearLayout1.addView(buttonsa.get(i));
}
//add remaining 5 to second layout
for (int i=5;i<10;i++){
linearLayout2.addView(buttonsa.get(i));
}
for (int i=10;i<15;i++){
linearLayout3.addView(buttonsa.get(i));
}
for (int i=15;i<20;i++){
linearLayout4.addView(buttonsa.get(i));
}
for (int i=20;i<25;i++){
linearLayout5.addView(buttonsa.get(i));
}
ll.addView(linearLayout1);
ll.addView(linearLayout2);
ll.addView(linearLayout3);
ll.addView(linearLayout4);
ll.addView(linearLayout5);
my create button function below:
private Button createButton(final int i) {
final Button b = new Button(this);
int mode = mGameSettings.getInt(GAME_PREFERENCES_GAME_MODE, 0);
if (mode == 1) {
b.setText(" "+letter[i]);
b.setWidth(20); <-- this is where I thought I could change but does not
b.setHeight(20); <-- same here, just fills the small screen with big image
and cuts of the rest.
}
else {
b.setText((i+1) +" "); }
