我有一个包含如下视图的布局:

<LinearLayout>
<TextView...>
<TextView...>
<ImageView ...>
<EditText...>
<Button...>
</linearLayout>

如何以编程方式在我的EditText上设置焦点(显示键盘)?

我已经尝试过了,它只在我正常启动我的活动时才起作用,但当我在TabHost中启动它时,它不起作用。

txtSearch.setFocusableInTouchMode(true);
txtSearch.setFocusable(true);
txtSearch.requestFocus();

这对我很有效, 多亏了ungalcrys

显示键盘:

editText = (EditText)findViewById(R.id.myTextViewId);
editText.requestFocus();
InputMethodManager imm = (InputMethodManager)getSystemService(this.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,InputMethodManager.HIDE_IMPLICIT_ONLY);

隐藏键盘:

InputMethodManager imm = (InputMethodManager) getSystemService(this.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);

其他回答

final EditText tb = new EditText(this);
tb.requestFocus();
tb.postDelayed(new Runnable() {
    @Override
    public void run() {
        InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        inputMethodManager.showSoftInput(tb, InputMethodManager.SHOW_IMPLICIT);
    }
}, 1000);

这里是KeyboardHelper类,用于隐藏和显示键盘

import android.content.Context;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;

public class KeyboardHelper {
public static void hideSoftKeyboard(final Context context, final View view) {
    if (context == null) {
        return;
    }
    view.requestFocus();
    view.postDelayed(new Runnable() {
        @Override
        public void run() {
            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null;
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}, 1000);
}

public static void hideSoftKeyboard(final Context context, final EditText editText) {
    editText.requestFocus();
    editText.postDelayed(new Runnable() {
        @Override
        public void run() {
            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null;
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
}
}, 1000);
}


public static void openSoftKeyboard(final Context context, final EditText editText) {
    editText.requestFocus();
    editText.postDelayed(new Runnable() {
        @Override
        public void run() {
            InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null;
imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
}
}, 1000);
}
}

这些答案我一个都找不到。我的解决方案是将它们结合起来:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
editText.requestFocus();
imm.showSoftInput(editText, InputMethodManager.SHOW_FORCED);

我不确定为什么这对我来说是必需的——根据文档,似乎这两种方法都应该单独起作用。

我尝试了很多方法,但它不起作用,不确定是因为我使用共享过渡从片段到包含编辑文本的活动。

顺便说一句,我的编辑文本也包装在线性布局。

我添加了一个轻微的延迟来请求焦点,下面的代码对我来说是有效的: (芬兰湾的科特林)

 et_search.postDelayed({
     editText.requestFocus()

     showKeyboard()
 },400) //only 400 is working fine, even 300 / 350, the cursor is not showing

showKeyboard ()

 val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
 imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0)

这对我很有效, 多亏了ungalcrys

显示键盘:

editText = (EditText)findViewById(R.id.myTextViewId);
editText.requestFocus();
InputMethodManager imm = (InputMethodManager)getSystemService(this.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,InputMethodManager.HIDE_IMPLICIT_ONLY);

隐藏键盘:

InputMethodManager imm = (InputMethodManager) getSystemService(this.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
