问题描述

我想添加一个搜索查看来材料设计工具栏 / 动作条，使得搜索查看默认情况下会扩大，占据了整个空间的工具栏宽度 - 明智。我有以下工具栏为止。

输入图像的描述在这里

与它的问题是：的

  1. 我要搜索图标有从屏幕的左边缘的距离相同的的 X 图标从屏幕右边缘。 我怎么能这样做？

  2. X 图标只有当我开始输入搜索查询，然后消失，如果我取消由pressing它的查询显示。我想这是有尽快工具栏显示（这只要活动似乎是），而只是停留，即使没有搜索查询（按类型用户）有与搜索提示文本是可见的。 我怎么能这样做？

我的尝试：的

我尝试添加安卓contentInsetStart ，安卓contentInsetLeft ，应用程序：contentInsetStart 和应用：contentInsetLeft 到工具栏 XML，这并没有帮助。然后我试图找到工具栏（通过findViewById（））从的onCreate（）的活动，然后做了 toolbar.setContentInsetsAbsolute（0,0 ）; 。 无论是帮助。

然后我试图加入 setSupportActionBar（工具栏）来的onCreate（）和 ActionBar.LayoutParams PARAMS =新ActionBar.LayoutParams（ActionBar.LayoutParams.MATCH_PARENT ，ActionBar.LayoutParams.MATCH_PARENT）;         sea​​rchView.setLayoutParams（PARAMS）; 在onCreateOptionsMenu（），但不成功

我相信

 安卓contentIntentStart =0dp
    机器人：contentIntentLeft =0dp
    应用程序：contentIntentStart =0dp
    应用程序：contentIntentLeft =0dp

的意思是

I am trying to add a SearchView to Material Design Toolbar/ActionBar such that the SearchView is expanded by default and takes up the entire space of the Toolbar width-wise. I have the following Toolbar so far.

The problem with it is:

  1. I want the Search icon to have the same distance from the left edge of the screen as that of the X icon from the right edge of the screen. How can I do that?

  2. The X icon appears only when I start typing a search query, and then it disappears if I cancel the query by pressing it. I want it to be there as soon as the Toolbar appears (which is as soon as the Activity appears), and just stay even when there is no search-query (typed by the user) there and the search hint text is visible. How can I do that?

WHAT I TRIED:

I tried to add android:contentInsetStart, android:contentInsetLeft, app:contentInsetStart and app:contentInsetLeft to the Toolbar XML, which did not help. Then I tried to find the Toolbar (by findViewById()) from onCreate() of the Activity, and then did toolbar.setContentInsetsAbsolute(0,0);. Neither helped.

Then I tried adding setSupportActionBar(Toolbar) to onCreate() and ActionBar.LayoutParams params = new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.MATCH_PARENT); searchView.setLayoutParams(params); in onCreateOptionsMenu(), but in vain.

SSCCE CODE:

MainActivity.java

public class MainActivity extends AppCompatActivity {
    private TextView textView;
    private Toolbar toolbar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        textView = (TextView) findViewById(R.id.mainActivity_textView);
        toolbar = (Toolbar) findViewById(R.id.mainActivity_toolbar);

        setSupportActionBar(toolbar);

        toolbar.setContentInsetsAbsolute(0,0);


        handleIntent(getIntent());
    }

    @Override
    protected void onNewIntent(Intent intent) {
        setIntent(intent);
        handleIntent(intent);
    }

    private void handleIntent(Intent intent) {
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
          String query = intent.getStringExtra(SearchManager.QUERY);
          doMySearch(query);
        }
    }

    private void doMySearch(String searchQuery) {
        textView.setText(searchQuery); 
    }

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

        // Inflate the options menu from XML
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main, menu);

        // Get the SearchView and set the searchable configuration
        SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        MenuItem searchMenuItem = menu.findItem(R.id.action_search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchMenuItem);
        // Assumes current activity is the searchable activity
        searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        //searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default

        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();
        return super.onOptionsItemSelected(item);
    }
}

解决方案

I believe that

    android:contentIntentStart="0dp"
    android:contentIntentLeft="0dp"
    app:contentIntentStart="0dp"
    app:contentIntentLeft="0dp"

was meant to be

    android:contentInsetStart="0dp"
    android:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    app:contentInsetLeft="0dp"
