我有一些佈局文件編程方式添加布局,我嘗試以編程 添加新的RelativeLayout這是我的XML佈局文件在Android的按鈕偵聽
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/mainlayout"
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<RelativeLayout
android:id="@+id/rot"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="#ff0000" >
<ImageView
android:id="@+id/btn_categorry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginRight="12dp"
android:background="@drawable/ic_launcher" />
</RelativeLayout>
這是java代碼
public class MainActivity extends Activity {
RelativeLayout myImage, mainlayout;
private ImageView img;
RelativeLayout staticlayout;
RelativeLayout.LayoutParams parms;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myImage = (RelativeLayout) findViewById(R.id.rot);
mainlayout = (RelativeLayout) findViewById(R.id.mainlayout);
img = (ImageView) findViewById(R.id.btn_categorry);
parms = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
img.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
staticlayout = new RelativeLayout(getApplicationContext());
staticlayout.setBackgroundColor(Color.parseColor("#000000"));
ImageView add_btn = new ImageView(getApplicationContext());
add_btn.setBackgroundResource(R.drawable.ic_launcher);
RelativeLayout.LayoutParams parms2 = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
parms2.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
parms2.addRule(RelativeLayout.CENTER_HORIZONTAL);
add_btn.setLayoutParams(parms2);
add_btn.setOnClickListener(new listener());
staticlayout.setId(10);
staticlayout.addView(add_btn);
parms.addRule(RelativeLayout.BELOW, R.id.rot);
staticlayout.setLayoutParams(parms);
mainlayout.addView(staticlayout);
}
});
}
class listener implements OnClickListener {
@Override
public void onClick(View v) {
RelativeLayout.LayoutParams costomparam = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
RelativeLayout relativelayout = new RelativeLayout(
getApplicationContext());
relativelayout.setBackgroundColor(Color.parseColor("#AB3232"));
ImageView add_btn = new ImageView(getApplicationContext());
add_btn.setBackgroundResource(R.drawable.ic_launcher);
RelativeLayout.LayoutParams imagelayoutparam = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
imagelayoutparam.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
imagelayoutparam.addRule(RelativeLayout.CENTER_HORIZONTAL);
add_btn.setOnClickListener(new listener());
add_btn.setLayoutParams(imagelayoutparam);
relativelayout.addView(add_btn);
costomparam.addRule(RelativeLayout.BELOW, staticlayout.getId());
relativelayout.setLayoutParams(costomparam);
mainlayout.addView(relativelayout);
}
}
}
我試着解釋我的問題。我可以在新的佈局(我創建了
以編程方式)添加新的佈局和圖像視圖,並且我還可以添加新的佈局按鈕點擊一個按鈕我也以編程方式創建。 現在我想編寫代碼來創建新的佈局每次。我想遞歸函數。我可以解決我的問題? 如果有人知道解決問題,請幫我
