我想创建以下适用于每种类型平板电脑的布局。我知道我们可以通过将它们放置在可绘制对象中并对其进行编辑来设置不同的设置,但是是否有替代方法来实现呢?以下是我为所有 7 英寸尺寸的平板电脑创建的意图:
以下是我的xml代码:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="@+id/widget38"
android:layout_width="480dp"
android:layout_height="45dp"
android:background="@color/White"
android:text="Reminder"
android:textSize="20dp"
android:textColor="@color/Black"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" />
<TextView
android:id="@+id/label"
android:layout_width="476dp"
android:layout_height="70dp"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_below="@+id/widget38"
android:background="@color/White"
android:text="DID you have your Pill?"
android:textColor="@color/Black"
android:textSize="40dp" />
<Button
android:id="@+id/yes"
android:layout_width="224dp"
android:layout_height="161dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignRight="@+id/widget38"
android:layout_below="@+id/label"
android:background="@color/Green"
android:text="Yes" />
<Button
android:id="@+id/no"
android:layout_width="239dp"
android:layout_height="161dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_below="@+id/label"
android:layout_toRightOf="@+id/widget38"
android:background="@color/Red"
android:text="No/Cancel" />
</RelativeLayout>
我创建警报的java代码:
Button button=(Button)findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
@SuppressWarnings("deprecation")
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
View view= getLayoutInflater().inflate(R.layout.custom, null);
final AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setView(view);
// set the custom dialog components - text, image and button
TextView t=(TextView)view.findViewById(R.id.widget38);
TextView text = (TextView)view.findViewById(R.id.label);
Button yesButton = (Button) view.findViewById(R.id.yes);
Button noButton=(Button)view.findViewById(R.id.no);
final AlertDialog dialog=builder.create();
noButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
yesButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
dialog.show();
dialog.getWindow().setLayout(width, height);
根据答案编辑了代码,它在 Eclipse IDE 中正确显示,但是在模拟器上尝试时,它看起来非常不同。无法背诵..请帮助。
