Question

我的活动有两个片段。一个是列表，另一个是详细信息。每个的重量分别为1和3。现在我要做的是当用户点击其中一个列表对象时，另一个片段将从屏幕右侧弹出，占据屏幕的1/5左右，所以基本上权重应该是1,3和1但是发生的事情是，第三个片段占据了屏幕的近95％。

这是我的代码：

public class BracketActivity extends TorneyoBaseActivity implements Fragment2FragmentCommunicator {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_bracket);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_bracket, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    public void loadItemToDetailFragment(Object item) {
        if(item instanceof Bracket){
            Bracket data = (Bracket) item;
            FragmentManager manager = getSupportFragmentManager();
            BracketDetailFragment bracketDetailFragment = (BracketDetailFragment) manager.findFragmentById(R.id.activity_fragment_bracket_detail);
            bracketDetailFragment.loadBracket(data);
            showMatchFragment();
        }
    }

    MatchListFragment matchFragment;
    public void showMatchFragment(){

        LinearLayout linearLayout = (LinearLayout) findViewById(R.id.activity_bracket_container);

        FragmentManager fm = getSupportFragmentManager();
        matchFragment = (MatchListFragment) fm.findFragmentByTag("MatchListFragment");
        if (matchFragment == null) {
            FragmentTransaction ft = fm.beginTransaction();
            matchFragment = new MatchListFragment();
            ft.add(linearLayout.getId(), matchFragment, "MatchListFragment");
            ft.commit();
        }
    }
}

这是被称为

的片段

public class MatchListFragment extends Fragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        //return super.onCreateView(inflater, container, savedInstanceState);
        View view = inflater.inflate(R.layout.fragment_match_list, container, false);


        LinearLayout.LayoutParams param = (LinearLayout.LayoutParams) view.getLayoutParams();
        param.weight = 1.0f;
        view.setLayoutParams(param);
        return view;
    }
}

看起来重量调整似乎不起作用。这就是atm的样子。

</LinearLayout>

Answer 1

以下步骤步骤1-添加线性布局宽度0dp 步骤2-添加线性布局权重，无论您的设计如何重量= 1 步骤3-添加线性布局根元素权重总和，如weight = 4 现在检查。

我希望这一步能帮到你。

动态调用后如何调整片段的权重？
