想做個界面，要做圖形的button，每行四個，排7行，平均排列每行每列，如圖1，但現在圓行button會被拉伸，如圖2
求大神指點。在任何大小界面下都可以是圓形button，而且平均排列，間距一樣
附上代碼：
主代碼：
public class MainActivity extends AppCompatActivity {
private static String[] irButtonName ={
"CH1","CH2","ON","LOCK","10","50","OFF","AUTO","100","300","SENS+","TEST","500",
"1000","SENS","SemiAuto","2000","24H","EYE","PULSE","30S","1m","3m","5m",
"10m","20m","30m","60m"
};
private LinearLayout contentView; //宣告一個布局檔案的參考
private View.OnClickListener btnOnClick; //宣告button監聽的參考
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_main);
contentView = (LinearLayout) findViewById(R.id.contentView);
this.initView(contentView);
}
public void initView(LinearLayout parentLL){
// LinearLayout parentLL = (LinearLayout) contentView;
int size = irButtonName.length;
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT); //每行的水平LinearLayout 的引數
layoutParams.setMargins(10,23,10,23);
ArrayList<Button> childBtns = new ArrayList<Button>();
int totoalBtns=0; //添加到第幾個 button了
int yy=0;
for (int i=0;i<size;i++){
String item = irButtonName[i];
LinearLayout.LayoutParams itemParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT); //button的布局引數
int length = item.length();
itemParams.weight=3;
itemParams.width=0;
totoalBtns++;
yy++;
System.out.println("AddButton :"+"add =--------- "+yy);
// itemParams.width = 0;
itemParams.setMargins(55,5,55,5);
Button childBtn =(Button) LayoutInflater.from(this).inflate(R.layout.button,null);
//創建Button
// childBtn.setText(item);
// childBtn.setTag(item);
childBtn.setLayoutParams(itemParams); // 設定button的布局引數
childBtns.add(childBtn); //Add List
if(totoalBtns>=4){
totoalBtns=0;
LinearLayout horizLL = new LinearLayout(this);
horizLL.setOrientation(LinearLayout.HORIZONTAL);
horizLL.setLayoutParams(layoutParams);
for (Button addBtn:childBtns)
{
// Log.d("AddButton","add"+"="+addBtn.getText());
System.out.println("AddButton :"+"add = "+addBtn.getText());
horizLL.addView(addBtn);
}
parentLL.addView(horizLL);
childBtns.clear();
}
}
if(!childBtns.isEmpty()){
LinearLayout horizLL = new LinearLayout(this);
horizLL.setLayoutParams(layoutParams);
horizLL.setOrientation(LinearLayout.HORIZONTAL);
for (Button addBtn:childBtns){
horizLL.addView(addBtn);
}
parentLL.addView(horizLL);
childBtns.clear();
}
}
}
button.xm代碼如下： test.png=36*36
<?xml version="1.0" encoding="utf-8"?>
<Button xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/item_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:singleLine="true"
android:ellipsize="end"
android:background="@drawable/test"
android:textSize="18dp"
>
</Button>
content_main.xml代碼如下：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/contentView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:orientation="vertical">
</LinearLayout>

你得動態算寬度，然后讓每個button的高度=寬度uj5u.com熱心網友回復：
高度=寬度，一語點醒，十分感謝

為何不直接使用Recyclerview呢，簡單方便uj5u.com熱心網友回復：
畫一個圓用作背景，然后用GridView或者Recyclerview都可以轉載請註明出處，本文鏈接：https://www.uj5u.com/yidong/9267.html
