Android的 - 的LinearLayout水平，带包装的孩子 [英] Android - LinearLayout Horizontal with wrapping children

问题描述

有一个属性，为Android的LinearLayout中设置将使其能够正确地包裹子控件？

Is there a property to set for Android's LinearLayout that will enable it to properly wrap child controls?

意义 - 我有孩子的多变数量，并想水平奠定了他们这样的：

Meaning - I have changeable number of children and would like to lay out them horizontally like:

Example: Control1, Control2, Control3, ...

我这样做，通过设置：

I do that by setting:

ll.setOrientation(LinearLayout.HORIZONTAL);
foreach (Child c in children)
  ll.addView(c);

不过，如果我有大量的儿童，最后一个得到，而不是去下一行切断。

However, if I have large number of children, last one gets cuts off, instead of going to next line.

任何想法，这可怎么固定？

Any idea how this can be fixed?

推荐答案

对于任何人谁需要这种行为：

For anyone who needs this kind of behaviour:

private void populateLinks(LinearLayout ll, ArrayList collection, String header) {

    Display display = getWindowManager().getDefaultDisplay();
    int maxWidth = display.getWidth() - 10;

    if (collection.size() > 0) {
        LinearLayout llAlso = new LinearLayout(this);
        llAlso.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));
        llAlso.setOrientation(LinearLayout.HORIZONTAL);

        TextView txtSample = new TextView(this);
        txtSample.setText(header);

        llAlso.addView(txtSample);
        txtSample.measure(0, 0);

        int widthSoFar = txtSample.getMeasuredWidth();
        for (Sample samItem : collection) {
            TextView txtSamItem = new TextView(this, null,
                    android.R.attr.textColorLink);
            txtSamItem.setText(samItem.Sample);
            txtSamItem.setPadding(10, 0, 0, 0);
            txtSamItem.setTag(samItem);
            txtSamItem.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    TextView self = (TextView) v;
                    Sample ds = (Sample) self.getTag();

                    Intent myIntent = new Intent();
                    myIntent.putExtra("link_info", ds.Sample);
                    setResult("link_clicked", myIntent);
                    finish();
                }
            });

            txtSamItem.measure(0, 0);
            widthSoFar += txtSamItem.getMeasuredWidth();

            if (widthSoFar >= maxWidth) {
                ll.addView(llAlso);

                llAlso = new LinearLayout(this);
                llAlso.setLayoutParams(new LayoutParams(
                        LayoutParams.FILL_PARENT,
                        LayoutParams.WRAP_CONTENT));
                llAlso.setOrientation(LinearLayout.HORIZONTAL);

                llAlso.addView(txtSamItem);
                widthSoFar = txtSamItem.getMeasuredWidth();
            } else {
                llAlso.addView(txtSamItem);
            }
        }

        ll.addView(llAlso);
    }
}
